In honor of Star Trek 's 50th anniversary this month, The Hollywood Reporter counted down the top 100 episodes of Star Trek — ranking them across all six TV series with help from the stars and writers who made them so beloved.

Now we're going to break it down even further — this time organizing the episodes by era. Every day through Friday, we'll be releasing a new list specific to each series, with the order is based on our original list of 100. 

Here, we look at the best of the original series, which ran from 1966-69 saw Gene Roddenberry's vision brought to life by actors William Shatner (Spock), Leonard Nimoy (Spock), DeForest Kelley (Bones), Nichelle Nichols ( Uhura ), Walter Koenig ( Chekov ), George Takei ( Sulu ), and James Doohan (Scotty).

Below you'll find Shatner and Koenig reveal their favorite episodes, as well as hear from  Star Trek Beyond director Justin Lin, two iconic Trek writers and many more.

"We had bee spending too much money by the network's reckoning, so we had less to spend on this particular episode," recalls Walter Koenig of the hour, which saw an away team forced to battle in an Old West-style gunfight. "It gave my character some interesting work. He got the girl, he died and came back to life. I loved the whole concept." 

'Star Trek': Walter Koenig on Lean Years After Cancellation and How Writing Ultimately Saved Him

"the galileo seven".

Not only does this episode give us the first appearance of a shuttlecraft in Trek lore, it introduces a version of the concept that would become key to the franchise decades later — that there is a push and pull between the needs of the many and the needs of the few. The Enterprise is on a mission to deliver relief supplies to a colony. Meanwhile, seven  crewmembers  — including Spock and Bones — crash land on a hostile planet, and Kirk must grapple with holding out hope for them and delivering the relief supplies. 

"A Taste of Armageddon"

"This was the first Original Series episode I ever saw and it still blows my mind," says Jordan Hoffman, U.S. Film Critic for The Guardian and host of ENGAGE: The Official Star Trek Podcast . "Kirk is escorting a diplomat to a system of planets that have been in conflict for centuries. However, to protect their society’s infrastructure and maintain their culture, they don’t fight with weapons. Computers determine where phantom missiles hit and if your number comes up, you are ordered into a disintegration chamber. It is up to the Enterprise to intervene (which they totally aren’t supposed to do) and stop this insanity. It’s a rich concept with thrills, action, great speeches and even some humor. (Indeed, Spock takes the time to make a solid joke before sending someone crumpled to the floor with his Vulcan nerve pinch.)"

"The Doomsday Machine"

If Star Trek had shown Starfleet at its best until now, audiences got to see the flipside in this episode, in which Commodore Matt Decker (William Windom ) turns into an outer space Ahab chasing the cosmic Moby Dick of the episode's title: a "planet killer" that had nearly destroyed his own ship and killed everyone on board except for him. For an episode with such stakes, it's a surprisingly subtle story: While we should be worried about whether the planet killer can be stopped, the real tension comes from watching Decker struggle to deal with his trauma. 

"The Corbomite Maneuver"

The first episode to be filmed after the two different pilots for the series, " Corbomite " manages to sum up everything that makes the original series so special, with a tense yet optimistic take on the idea of first contact between the Enterprise and an alien race that shows how fearless, compassionate and sneaky Captain James T. Kirk can be when pressed, and a Twilight Zone -esque last-second twist. As if that wasn't enough to make this episode worthwhile, it features the first times that DeForest Kelley and Nichelle Nichols played McCoy and Uhura — although by the time the episode aired, they were well-established characters to the loyal audience.

"Journey to Babel"

"I've always loved 'Journey to Babel,' by Dorothy Fontana," says writer David Gerrold when asked about his favorite Star Trek episode. "Because it reveals so much about Spock, and his past, and his parents." That's putting it mildly; before this episode, it's unlikely that anyone would have given much thought about the parents of any of the crew, but the introduction of Spock's estranged parents — one of whom was human, the other suspected of murdering a fellow diplomat on board the Enterprise — changed the way audiences looked at the characters forever: suddenly, they were more than just their jobs, and had inner lives and struggles that everyone could relate to. And all because the most alien of all of the crew had proven himself to be just as human as the rest of us.

"All Our Yesterdays"

While the final episode of the original series — "Turnabout Intruder" — is generally considered to be a low point for the show, the second last episode throws Spock, McCoy and Kirk back in time and puts them all out of their comfort zones as a result, with McCoy having to be the practical one, Spock becoming overwhelmed by emotions and Kirk on his own against the authorities. Yes, the title sounds like a soap opera (It's actually from Shakespeare, specifically Macbeth ), but this is a particularly strong Star Trek episode through and through. 

"The Enterprise Incident"

Justin Lin, who directed this summer's Star Trek Beyond , picks this tale of intrigue as his favorite. 

"A good old-fashioned spy thriller set in the Neutral Zone. What’s not to love?" Lin asks. "We get to see my favorite version of Kirk: the tactician. His ruse is brilliant and daring, but it’s Spock who steals the show in his interaction with the female Romulan commander. We see him in rare form, opening up his human and—dare I say—sexual side. Of course, Kirk’s ploy succeeds and the cloaking device is stolen, but Spock derides the fleeting nature of such military victories and says to the female commander something emblematic of everything great about Star Trek : 'I hope that you and I have exchanged something more permanent.' "

The episode was loosely inspired by a real-life incident where the USS Pueblo was attacked by North Korean forces after being accused of sailing into its territory in January 1968.

"The Menagerie"

Mr. Spock commits mutiny on the Enterprise in order to get Christopher Pike, his former commander, back to the forbiden planet  Talos IV.  We eventually learn that years earlier, Pike and Spock visited the planet, where Pike was horribly mutated — and Spock is trying to get his former commander there to be healed. 

"It is a story of Spock’s loyalty to his former commander as well as to Captain Kirk and of Spock’s bravery as he risks his own career and reputation," recalls Adam  Nimoy , son of Leonard  Nimoy  ad director of For The Love of Spock , which hits theaters Sept. 9. "Although he refuses to admit to it, Spock sets aside logic to do the right thing, and I just loved it."

How Nearly Refusing 'Star Trek III' Reinvigorated Leonard Nimoy's Career

"amok time".

For fans who'd spent the show's first year swooning over Leonard Nimoy's pointy-eared alter-ego, second season opener "Amok Time" was everything they could've hoped for and more: Not only did they get to go back to Spock's home planet, they also got to see two things they'd dreamt of but never expected: Spock in the throes of passion — apparently, Vulcans are very like dogs in heat every seven years — and Spock fighting Kirk to the death … or, at least, that's what it seemed like at the time. Written by noted sci-fi author Theodore Sturgeon, this episode showed that Trek 's second year would be, if anything, even bolder than its first.

"The Devil In The Dark"

"The Horta has a funny story," says original series story editor D.C. Fontana of the episode's alien. " Stuntman , actor, creature creator Janos Prohaska  did creature work for us. [Writer] Gene Coon, Gene Roddenberry and I were in the office and Janos came in and said, 'Come outside, I want to show you guys something.' So we went outside, and here's this a lump of what looked like foamy bubbles. He said, 'Just watch,' and laid a rubber chicken out on the street, and crawls into this rubber bubble suit and crawls towards the rubber chicken and the chicken disappears and a trail of bones comes out the back. Roddenberry , Coon and I were laughing our heads off, and Gene Coon said, 'I've got to do something with that.' "

That something turned out to be the Horta , an alien threat who isn't so sinister after all. 

"You think it's a monster killing the miners, and you find out it's a mother protecting its young!" says Fontana. "That was the first time we did the Vulcan mind meld, and that turned out well, but we also found that this alien isn't what you think it is. There's a human aspect that we can understand and begin to work with this thing."

"The Naked Time"

[youtube https://www.youtube.com/watch?v=M58aP5DtNqY]

A swashbuckling (and shirtless) Sulu is perhaps the single most enduring image from the original series, with the officer infected with a virus provoking him to act out his inner most desires. George  Takei  had just three weeks of "frantic fencing lessons" to prepare for his scenes, he recalled in his 1994 autobiography, To The Stars . Days before shooting, director Marc Daniels dropped another surprise: he would be performing the scenes shirtless. "Straightaway, I got down horizontally on the floor, put my feet on the couch, and began pumping out push-ups to build up a photogenic chest," Takei  recalled in his book.

"Where No Man Has Gone Before"

[youtube https://www.youtube.com/watch?v=QT4fm0f2lZY]

After the first Star Trek pilot failed to catch fire, Roddenberry enlisted Gary Lockwood, who was about to shoot  2001: A Space Odyssey  and had worked with the Star Trek creator on  The Lieutenant. Trek producers believed Lockwood's involvement could help seal the deal — and they also brought on a new captain (Kirk) as well as Mr. Scott and  Sulu . In the story, Kirk must grapple with the value of human life after an old friend and shipmate Gary Mitchell (Lockwood) gains dangerous (and growing) power from the edge of the galaxy. 

"The pilot sells, and 20 years later Roddenberry said to me that Gary Mitchell was the character that got Star Trek on television," says Lockwood.

On the surface, it's an episode about Kirk fighting a giant lizard man, but it's about so much more. Namely: humanity, ingenuity and ultimately, mercy. After being forced to fight to the death, Kirk spares the life of the  Gorn . Those impressive Gorn sounds were courtesy of Ted Cassidy, best known as Lurch on another ' 60s classic,  The Addams Family . The image of Kirk fighting the Gorn is so indelible that even if you don't know the alien's species, you know his green skin.

"The Trouble With Tribbles"

[youtube https://www.youtube.com/watch?v=B2T1QX7BEyg]

Writer David Gerrold credits his interest in ecology with the origins of this classic episode. "I'd heard about rabbits getting out of control in Australia," he remembers, " and I thought, this is a very weird, very funny effect of introducing an invasive species into an environment without an appropriate predator. So, I was thinking for Star Trek , not all the aliens we meet are going to be scary or ugly — some of them are going to be cute and friendly and we're not going to recognize what kind of danger they are until it's too late." The teleplay was Gerrold's first professional credit, and he worked hard to make it the best that he could. "I had studied the Star Trek structure very carefully and put every scene on a 3 by 5 card until each scene demanded that the next scene followed," he says. "As funny as the script turned out, I was proudest of the structure of the episode. You could take all the jokes out, and it would still work as an adventure."

"Let That Be Your Last Battlefield"

[youtube https://www.youtube.com/watch?v=STQNi7ArRl8]

It's understandably challenging for William Shatner to pin down a favorite episode among all the greats, but when pressed, he chooses this one. The hour sees guest star Frank Gorshin play an alien, whose face is half black and half white and who hates those of his species with the colors reversed. 

"That beautiful concept, without shaking a finger, illustrated the ridiculousness of race hatred, and it was very entertaining as well. The magnificence of the idea is obvious," says Shatner . The actor says part of the brilliance of Trek is its ability to entertain without preaching.

"We use to say, 'You send a message by telegram. Make [your show] entertaining," says Shatner . "But when you can combine both, like that idea, it becomes both dramatic and obvious. And you become aware. Those were the best of the Star Trek episodes."

"Mirror, Mirror"

[youtube https://www.youtube.com/watch?v=_oOqQ38XLv8]If Star Trek gave anything to the world, it's the idea that evil versions of characters have goatees, an idea ironically put forward by the Spock of the Mirror Universe — who isn't actually evil , per se. That's a good thing, because if he had been, it's possible that Kirk, Bones, Scotty and Uhura might have been trapped in the morally-flipped alternate timeline for good, having to deal with the stomach-bearing outfits for women, the workplace harassment nightmare that is the Agonizer and George Takei's wonderfully over-the-top Evil Sulu for the rest of their fictional lives. A fun look at the roads not taken (including a more military-focused Starfleet), this episode would go on to inspire sequels in both Deep Space Nine and Enterprise . 

"Space Seed"

[youtube https://www.youtube.com/watch?v=B_c1Odol9xw]

No Star Trek episode has paid off quite like this one. Ricardo Montaban's single appearance on the original series as the 1990s  warlord Khan Noonien Singh set the stage for the undisputed greatest  Star Trek film ever, The Wrath of Khan , set 15 years after Kirk and the Enterprise stumbled upon the Botany Bay. "Space Seed" sees Kirk fight his intellectual and physical superior — and win despite the long odds. Nothing is more Kirk than that. 

"Balance of Terror"

[youtube https://www.youtube.com/watch?v=JGn948_PXTU]

The acclaimed episode was inspired by submarine warfare and introduces the Romulans , with whom the Enterprise engages in a claustrophobic game of cat and mouse. The episode tackles themes such as the futility of war and xenophobia, with Mr. Spock facing discrimination from his own crew when it is revealed that Romulans and Vulcans not only look similar, but also share a common heritage. 

"City on the Edge of Forever"

[youtube https://www.youtube.com/watch?v=KFqD7s-A6VU]

Never mind the behind-the-scenes controversy. Credited writer Harlan Ellison was heavily rewritten by  Roddenberry , D.C. Fontana and others before the episode was shot, and decades later sued CBS for a share of profits from the episode. Just enjoy one of the true classic hours of science fiction TV as a dazed and confused McCoy travels back in time and accidentally rewrites history, forcing Kirk and Spock to follow and learn firsthand how hard it is to do the right thing for the greater good.

"I knew this episode was going to be special, not because I’m prescient, but because a couple of months earlier, I had interviewed series creator Gene  Roddenberry  for the  Daily Sundial , the campus newspaper at San Fernando Valley State College," recalls journalist Fred Bronson, who would go on to form a friendship  Roddenberry . "Aside from telling me that the purpose of television was to sell toothpaste,  Roddenberry  talked about an episode that had been recently filmed that he said was good enough to be a motion picture — and long enough as well, as they had to delete a lot of footage in order to make it fit the hour-long slot."

For fans of unexpected celebrity appearances, the love interest in this episode? None other than Joan Collins

"The best episodes of Star Trek (or any series) were always the ones where you absolutely believed everything that was happening was real and that you were not being manipulated by the writer," says Bronson. " 'The City on the Edge of Forever' felt authentic from the opening scene on the bridge of the Enterprise to the heartbreaking ending, when Capt . Kirk must allow the love of his life, social worker Edith Keeler , to die in a traffic accident. For years, I couldn’t watch reruns of that final scene without bursting into tears. From Spock’s declaration that trying to create a mnemonic circuit in the America of the 1930s was working with 'equipment…hardly very far ahead of stone knives and bear claws' to Kirk’s explanation to a police officer that Spock’s ears were the result of a childhood accident involving a 'mechanical rice-picker,' the dialogue of this classic episode is etched in my brain as the story that will live forever as Star Trek ’s finest hour."

Star Trek Changes Its Iconic Tribbles Forever, With Shock Revelation About Their Biology

Star trek explains why it uses 'quadrants' despite the universe being infinite, i’m glad voyager’s tom and b’elanna are no longer star trek's only successful romance.

As fans are rejoicing about currently having 5 Star Trek series in production at the same time, they might consider returning to the impetus of Gene Roddenberry's vision of the future in  Star Trek: The Original Series .  So much of the material that makes up the foundation of Star Trek lore, foundation, and canon comes from the '60s sci-fi classic, with plot points and storylines strongly felt in  Star Trek: Picard   and to an even greater extent in  Star Trek: Discovery.

RELATED:  Which One Is Better, Star Trek The Original Series Or TNG?

The five-year mission of Captain Kirk, Mr. Spock, Doc McCoy, and the rest of the crew of the starship Enterprise was full of everything from ethical questions regarding the humanity of artificial intelligence, to political intrigue pitting the Federation against Romulan insurgents. It also introduced fan favorites, from the Vulcan salute to the Mirror Universe. Boldly go where you've already gone before with these 15 classic episodes of  Star Trek: The Original Series.

Updated on December 3rd, 2021 by Kayleena Pierce-Bohen: With a brand new season of Star Trek: Discovery, Star Trek: Picard, and Star Trek: Lower Decks , a brand new spin-off series Star Trek: Strange New Worlds , and the all-new animated show Star Trek: Prodigy , it's the perfect moment   to revisit the very best Star Trek: The Original Series episodes. Many of the characters, plots, and themes contained in this prestigious catalog have found their way into the current Star Trek canon, and continue to be appreciated for the perspective and insight they give fans today.

"Spectre Of The Gun" (Season 3, Episode 6)

Don't let the premise fool you -- one of the best Star Trek   TOS  episodes involves an old-fashioned Western showdown . When Kirk gets sentenced to death on a hostile planet, he's only given the most primitive weapons to wage battle -- a pair of six-shooters. Fans of Sci-fi Westerns should love the captain of the Enterprise and his bridge crew blasting their way through a gunfight at the OK Corral.

While  The Original Series  might have been restrained by budgetary restrictions, even the much slicker  Star Trek: The Next Generation   couldn't resist taking elements from this classic episode in "A Fistful of Datas", which sees the bridge crew in a very similar situation on the holodeck.

"All Our Yesterdays" (Season 3, Episode 23)

As a doomed planet hurtles towards its own annihilation, Captain Kirk spends the final hours perusing its library's vast database. Unfortunately, this removes over 50 centuries of knowledge of Vulcan civilization from Mr. Spock, throwing him into a vortex of emotions.

Taking a page from The Twilight Zone 's "Time Enough At Last", in which a book-obsessed bank clerk survives a nuclear attack and believes he has all the time in the world to read (but in fact doesn't), "All Our Yesterdays" (itself a reference to Shakespeare's "Macbeth") plays with a similar issue of cause and effect, and the concept of "be careful what you wish for", making it one of   the   best Star Trek TOS  episodes in its final season.

"The Menagerie (Parts I And II)" (Season 1, Episodes 11 And 12)

Before James Tiberius Kirk took command of the Enterprise, another captain sat in "the chair"; Christopher Pike (Jeffrey Hunter). He was featured in the original pilot for the series ("The Cage"), which ended up being combined with "The Menagerie" for the original series' only two-part episode. While less exuberant than Kirk, Pike was one of the first captains to openly discuss issues involving mental health.

RELATED:  Why Captain Pike Is The Best Enterprise Captain (& 5 Reasons It's Kirk)

The episode begins with Spock committing treason, taking command of the Enterprise, and abducting his former captain (who's suffered a horrific accident) to participate in a tense, mercurial courtroom drama. The episode is necessary viewing for background into Captain Pike's return in  Star Trek: Discovery. 

"The Galileo Seven" (Season 1, Episode 16)

Relief efforts in a mysterious solar system go awry when Mr. Spock and Co. accidentally crashland their shuttlecraft on Taurus II, where they're immediately attacked by a giant creature and depleted of resources. Aboard the Enterprise, Captain Kirk is forced to make an important decision -- continue the mission to deliver relief supplies to the colony, or wait to hear from Spock, Bones, and the rest of his friends.

The concept of placing the needs of the many over the needs of the few would continue to be a major touchstone in the franchise, and it's no better articulated than in "The Galileo Seven". The debut of the shuttlecraft to the lore is another first for one of the best  Star Trek  episodes in the canon.

"The Naked Time" (Season 1, Episode 4)

After the crew of the Enterprise passes through Psi 2000 in an effort to find answers to a research team's unexpected demise, a virus takes hold of them that makes them act out their most hidden desires. For Sulu, that means swashbuckling around the ship shirtless with a rapier and creating one of the most iconic images of the series.

Star Trek  canon would eventually be full of episodes of viruses making crew members behave irrationally ( Star Trek: The Next Generation  also did it early in its first season), but this episode is special because it's recounted with particular zest by George Takei, who explained in his autobiography  To The Stars  that he only had 3 weeks of fencing to prepare for the plot, and 3 days to prepare for appearing shirtless!

"Arena" (Season 1, Episode 18)

After a Federation outpost gets destroyed, the Enterprise makes hot pursuit, until coming into contact with a new and fearsome enemy -- the Gorn. Captain Kirk enters into a fight to the death in the slim chance that he might be able to save himself and his crew.

RELATED:  Every Star Trek TV Series Ranked By Popularity

While some fans might dismiss this episode as Kirk two-fist punching a lizard man, it's one of the best  Star Trek TOS  episodes because it ingeniously straddles the themes of humanity and mercy.  Even after they fight to the death, Kirk spares the Gorn's life (voiced by Ted Cassidy, who played Lurch on  The Addams Family   airing at the same time), an iconic end to an iconic moment in  TOS. 

"The Squire Of Gothos" (Season 1, Episode 17)

For the Enterprise crew, coming into contact with an omnipotent being isn't out of the ordinary, but few are as memorable as Trelane, the "Squire of Gothos". Located on a planet that should be uninhabited, Trelane becomes the focal point of an investigation by the Enterprise, and the crew spends an episode marveling at his 18th-century environment as he marvels at their technology.

Of course, Kirk and Co. soon discover that the anachronistic figure possesses godlike powers, and all their tech is no match for his shenanigans. They become trapped in a game of wits for his amusement, and they must beat Trelane to survive. The character inspired John DeLancie's infamous Q on  Star Trek: The Next Generation,  a celestial mischief-maker known for his obnoxious harassment of Captain Picard and his crew.

"The Enemy Within" (Season 1, Episode 6)

After a transporter accident, Captain Kirk is split into two different entities, a plot point which would be revisited in  Star Trek: The Next Generation  and  Star Trek: Voyager .  The episode becomes a study of the captain of the Enterprise, as each personality attempts to assert dominance over the Federation flagship.

One personality is domineering and hostile, while the other is incredibly passive. As the storyline progresses, it becomes something of a morality play, as it becomes increasingly clear that as each Kirk becomes his own man, it becomes a difficult task to determine who has the "right" to remain as the true James Tiberius Kirk.

"Journey To Babel" (Season 2, Episode 10)

There's a mystery aboard the Enterprise in "Journey to Babel", which marked the first time that representatives of the Federation's founding members were all together again on screen. Vulcans, Humans, Andorians, and Tellarites all appear to attend the Babel Conference, and later a murder occurs.

Not only is the episode full of classic Trek humor, intrigue, and galactic politics, it also reveals a lot about Spock's upbringing. His Vulcan father, Sarek , and human mother are also included in the mix, and Spock undergoes a great deal of character development thanks to the familial exchanges between them.

"The Corbomite Maneuver" (Season 1, Episode 11)

With many Star Trek series like  Star Trek: The Next Generation, Star Trek: Discovery,  and even  Star Trek: Picard  piggy-backing so many episodes of the original series with their plots and storylines, it's important to remember that what made it unique sometimes came down to Captain Kirk's captaincy.

In "The Corbomite Maneuver", the Enterprise encounters a mysterious alien intent on attacking it. Thanks to Kirk's quick thinking, he outmaneuvers its assault. The episode provides great insight into Kirk's tactical skill, and the original series' ability to create tension without the fancy visuals of  Star Trek: Discovery,  though we suspect Captain Lorca would approve of Kirk's plan.

"Let That Be Your Last Battlefield" (Season 3, Episode 15)

A stolen shuttlecraft boards the Enterprise and produces a fugitive from the planet Charon. The pilot, Lokai, has skin that's split down the middle; one side of him is black and the other white. A second shuttle soon arrives bearing Bele, also from Charon, who despises Lokai despite looking almost exactly like him; one side of him is white, and the other black.

RELATED:  10 Alien Species In Star Trek Explained

Conceptual sci-fi takes a very literal turn in "Let That Be Your Last Battlefield", where the perceived difference in their skin color causes Lokai and Bele to commit to a generations-old feud between their people. It confounds the Enterprise crew, who cannot imagine hating another being for a physical attribute they cannot change.

"The Trouble With Tribbles" (Season 2, Episode 15)

No  Star Trek  list would be complete without one of its most famous episodes, "The Trouble With Tribbles". The light-hearted plot finds the Enterprise docked at Space Station K-7, where fear-mongering has tarnished a Klingon visit and erupted in trade disputes. Uhura purchases what looks like a twittering ball of hair, but is in fact a Tribble - a pregnant one at that.

As the Tribbles begin to multiply exponentially , Kirk must balance Federation politics, the intricacies of grain supply and demand, and the burgeoning Tribble dilemma. The Tribbles proved so popular that they were featured again in "Trials And Tribble-ations" on  Star Trek: Deep Space Nine .

"A Taste Of Armaggedon" (Season 1, Episode 23)

While most  Star Trek  fans view Starfleet as an organization that represents the highest ideals of the Federation, its members occasionally come in contact with cultures that have seemingly evolved beyond even its utopian parameters. In "A Taste of Armageddon", the Enterprise visits a planet whose inhabitants have grown beyond combat, but not war itself, and as representatives of Starfleet, the crew judged them for their beliefs.

Rather than destroy itself with weapons, the culture encourages warfare to be acted out in an accurate simulation. Trouble arises when the Enterprise crew finds itself in a building marked "destroyed" by the simulation, but rather than turn themselves in for disintegration like other members of the population, they refuse to surrender. This action threatens to bring about real war in all its destructive capacity, but Kirk sagely suggests that without it, the people of Eminiar VII had muted its horror.

"Balance Of Terror" (Season 1, Episode 15)

Not only did "Balance of Terror" introduce the nefarious Romulans to Star Trek canon, but it also featured a pragmatic battle of wills between warriors that, as one Romulan commander relays so poignantly to Captain Kirk, could have been friends in another reality. It reminds viewers that neither men are good nor evil, simply men on missions.

Though the Federation had fought the Romulans 100 years prior, until the incident along the neutral zone that opens the episode, no Federation starships had engaged a Romulan vessel in the years since, making this the premier occasion for visual contact.

"The Doomsday Machine" (Season 2, Episode 6)

In one of the most harrowing episodes in Star Trek franchise history, a destructive machine goes out of control, sparking the sort of paranoia and fear that existed during the Cold War happening during the show's broadcast. Known as the Doomsday Machine, it's being hunted by Captain Kirk and Commander Decker in an attempt to prevent it from destroying entire planets.

While Kirk sees finding the location of the device as one of many missions he needs to complete in the Enterprise's five-year journey, Decker becomes increasingly obsessed. As Kirk nevertheless faces off against it, he continues to promote a message of peace despite the terrifying alternative.

"Space Seed" (Season 1, Episode 22)

This episode was highlighted by two major components of Trek branding - a memorable nemesis, and the presence of relentless optimism. Ricardo Montalban introduced one of the most iconic villains in the entire Star Trek franchise as Khan Noonien Singh, a former dictator of Asia in the wake of the 20th century Eugenics War.

Khan represented the lowest point of humanity and Earth, while Captain Kirk and Co. stood for the great strides that it would come to make between the 20th and 24th centuries. It's not only necessary Trek to view, but sows the seeds of a great rivalry in  Star Trek II: The Wrath of Khan.

"The Enterprise Incident" (Season 3, Episode 2)

Though The Federation may have outlawed cloaking technology by the time  Star Trek: The Next Generation  was on the air, in  Star Trek: The Original Series,  it was very much favored. The Federation went so far as to send Kirk and Spock aboard a Romulan vessel to obtain the details of its engineering.

This premise has been visited again in Season 1 of  Star Trek: Discovery,  with Klingons in place of Romulans, but a similarly bizarre romantic interlude occurs. In "The Enterprise Incident", Spock participates in an uncharacteristically malevolent seduction of a female Romulan for the sake of the mission, adding complexity and depth to his character.

"Amok Time" (Season 2, Episode 1)

The first appearance of pon farr in Star Trek history occurs in this memorable episode when Mr. Spock's ordinarily reserved equipoise is disrupted by the Vulcan mating ritual. The Enterprise is rerouted to Vulcan so Spock can take care of his needs with a pre-arranged partner, only to find that she prefers another mate.

Not only does the episode provide insight into another fascinating ritual in Vulcan life , but it also reveals another side to Spock and Kirk's friendship. Not even a fight to the death can drive a wedge between the two, though it's great fun seeing the ordinarily calm and collected Spock lose his cool Vulcan facade. It's also the premiere of the Vulcan salute!

"The City On The Edge Of Forever" (Season 1, Episode 29)

In one of the most revered episodes in the Star Trek canon, one of the most difficult questions in sci-fi is posed; should one person be allowed to die, if their death would keep history intact and save millions? The query is raised when Captain Kirk and Mr. Spock travel back in time to save a raving Doc McCoy, ending up in 1930's America.

The episode is important for not only setting a precedent for time-travel stories in future Star Trek episodes but also to demonstrate that Captain Kirk was capable of true love and William Shatner of genuine acting. Kirk's sacrifice of a future with Edith Keeler so that the future of Earth remains secure is one of the most profound ethical quandaries in the entire franchise.

"Mirror, Mirror" (Season 2, Episode 4)

Before this episode's plot became a huge story arc in  Star Trek: Discovery,  it captured the imagination of fans everywhere as they watched the usually sterling crew of the Enterprise be depicted as malicious conquerors in an alternate reality. A transporter incident sends Kirk and Co. to a parallel universe, where the only opportunity for advancement on a starship is through assassination.

In this "Mirrorverse", The Federation has been replaced by a Klingon-type organization called the Terran Empire. Captain Kirk behaves with the sort of brutal malevolence only glimpsed at in "The Enemy Within", and even a heavily scarred Sulu becomes a vengeful officer, in a reality where everyone is the polar opposite of Federation ideals.

The 10 best Star Trek: The Original Series episodes, ranked

It’s hard to imagine today, but back in the late 1960s, the original Star Trek was not considered a hit. The ambitious science fiction series was constantly on the brink of cancellation and was cut short only three years into its planned five-season run.

10. Mirror, Mirror (season 2, episode 4)

9. a taste of armageddon (season 1, episode 24), 8. the menagerie, parts i and ii (season 1, episodes 12 and 13), 7. the doomsday machine (season 2, episode 6), 6. the corbomite maneuver (season 1, episode 11), 5. the devil in the dark (season 1, episode 26), 4. the trouble with tribbles (season 2, episode 15), 3. where no man has gone before (season 1, episode 4), 2. the city on the edge of forever (season 1, episode 29), 1. balance of terror (season 1, episode 15).

However, it’s important to put Trek ’s apparent failure into historical context as, given that most markets in the U.S. had only three television channels to choose from, even a low-rated show like Star Trek was being watched by about 20% of everyone watching television on a Thursday night, or roughly 10 million households. This year’s season of HBO’s Succession was viewed by roughly 8 million households a week , which makes it a hit by today’s standards. Star Trek ’s audience only grew once it went into reruns in the early 1970s, and by the time Star Trek: The Motion Picture hit theaters in 1979, it was a genuine cultural phenomenon. Today, the Star Trek franchise is considered one of the crown jewels of the Paramount library.

Though arguably outshined by its most prosperous spinoff, Star Trek: The Next Generation , Star Trek: The Original Series holds up remarkably well for a vision of our future imagined nearly 60 years in our past. It’s a space adventure series that tackles social or political issues from what was, at the time, a daring and progressive perspective informed by the contemporary civil rights movement, sexual revolution, and backlash against the Vietnam War. Conveying these values through fanciful science fiction didn’t only allow its writers to get away with a lot of subversive messages, it also delivered them in a way that remains fun to watch decades later — fun enough that fans are willing to forgive when its ideas, or its special effects, crumble under modern scrutiny.

These 10 episodes, however, unquestionably stand the test of time, and thanks to the continuity-light nature of mid-20th century television, any one of them could be your first Star Trek episode. (Be aware, however, that the order in which classic Trek episodes are listed varies depending on the source. For our purposes, we’re using the numbering from streaming service Paramount+ .)

Even if you’ve never seen an episode of Star Trek , you’re bound to be at least a little familiar with Mirror, Mirror through cultural osmosis. In this 1967 classic, Captain Kirk (William Shatner), Dr. McCoy (DeForest Kelley), Lt. Commander Scott (James Doohan), and Lt. Uhura (Nichelle Nichols) are accidentally transported to an alternate universe, where they encounter dastardly evil versions of their beloved shipmates. Instead of the benevolent United Federation of Planets, this ship serves the fascist Terran Empire, which threatens to annihilate a peaceful planet for refusing to submit to itsrule. Our heroes are forced to pose as their evil counterparts while they search for a way home and try to avert the genocide they’ve been ordered to perform.

This all sounds heavier than it is — like much of classic Trek , Mirror Mirror is very camp, with brightly colored costumes, over-the-top performances, and a general sense of fun. The cast is clearly having a ball playing the wicked versions of their characters (or playing the good versions of their characters playing the wicked versions), and it’s no wonder why multiple future incarnations of Trek would return to the Mirror Universe, usually for wacky adventure episodes. (For a more grim and brutal take on this same concept, visit the back half of Star Trek: Discovery ’s first season.) However, Mirror, Mirror still comes complete with Trek ’s famous humanist optimism, as Kirk tries to convince this universe’s menacing, bearded Spock (Leonard Nimoy) that regimes ruled by fear are unsustainable and, therefore, illogical. Given enough time, peace and cooperation will always win out over hate and violence.

A Taste of Armageddon may not appear on many “Best Of” lists, but it’s 100% pure, uncut Star Trek . In this episode, Kirk and company visit Eminiar VII, a seemingly peaceful planet that is, in fact, embroiled in a centuries-long war with a neighboring world. Rather than fire actual bombs at each other, the combatants conduct simulated attacks, determine the hypothetical death toll, and then order the “dead” citizens to report to disintegration chambers. When Kirk and his landing party are recorded as casualties, they decide to put an end to Eminiar VII’s supposedly “civilized” method of warfare.

While Kirk arguably has no right to interfere with how this sovereign planet conducts its affairs, the point of A Taste of Armageddon is to reflect on America’s attempt to make constant military conflict more palatable, or even invisible to the average American. Or, in a larger sense, it’s a commentary on the ease with which a culture can become accustomed to death and violence, so long as it’s part of an established routine. Because these simulated bombings leave homes, industry, and even the military infrastructure itself totally unharmed, it’s easy to forget that Eminiar VII is even at war — that is, until it claims your life or the life of someone you love.

When even these losses are framed as necessary sacrifices to maintain normalcy, it minimizes the incentive to make peace. Kirk (and, by extension, writers Robert Hamner and Gene L. Coon) argues that war is revolting no matter how much you dress it up, and that it must be brutal, terrifying, and omnipresent for all involved, or else it will never stop. The past half-century of perpetual U.S. military intervention abroad has proven this thesis to be chillingly accurate.

If you’re watching Star Trek on Paramount+, you’ll notice that the episode it has listed as “season 1, episode 1,” The Cage , isn’t exactly the show you were expecting. Instead of the famous Captain James T. Kirk, the USS Enterprise is under the command of Captain Christopher Pike (Jeffrey Hunter), and apart from Mr. Spock — who smiles?! — the rest of the crew is also unfamiliar. That’s because The Cage is Star Trek ’s original pilot episode, which was rejected by NBC, leading to a second pilot being commissioned with a new cast and modified tone. The Cage wouldn’t air as its own episode until 1988, but during production of Star Trek ’s first season in 1966, a budget crunch led to writer/creator Gene Roddenberry repurposing footage from the already-completed pilot into a new script in the form of flashbacks.

This fiscally minded decision endowed Star Trek and its characters with a history, instantly making the universe a bigger and more interesting place. The two-part Menagerie sees Spock, the only remaining character from the original cast, commandeer the Enterprise for the sake of its previous captain, Christopher Pike. On the way to a forbidden planet, Spock uses mysterious footage from an adventure 13 years in the past to explain his rash actions.

If you’ve already watched The Cage , then The Menagerie will seem like a glorified clip show, in which Kirk and company spend half the runtime watching a previous episode. However, before the streaming era, The Cage was usually the last episode of The Original Series that a fan would see, rather than the first. In recent years, however, The Cage and The Menagerie have taken on a new role, as bookends to the adventures of Christopher Pike, as portrayed by Anson Mount on modern spinoff Star Trek: Strange New Worlds . Strange New Worlds (as well as the second season of Star Trek: Discovery ) take place after The Cage , but before The Menagerie , allowing us to get to know Kirk’s predecessor in his own context, as well as developing the bond between Pike and Spock that will eventually drive the Vulcan to mutiny. Even without any of this context, however, The Menagerie is an exciting two-hour event, an eras-spanning mystery that will make you wonder why NBC passed on the Star Trek pilot in the first place.

Due to the production constraints of 1960s television, the original Star Trek didn’t often aim for large-scale, awe-inspiring space action. The Doomsday Machine is the closest that classic Trek ever came to “epic,” and as compelling a story as it is, it’s also Exhibit A as to why such a thing was impractical with the resources available. Though its original effects required no small amount of ingenuity (they couldn’t afford to give their Enterprise model battle damage, so they bought one off the rack from a toy store and distressed it), the results look mighty corny on a modern high-definition television.

Still, the episode gained fame as boasting the largest-scale action of the series, as the Enterprise teams up with her badly damaged sister ship, the USS Constellation, to take on a huge planet-eating weapon. It also presages a theme that would become common in Star Trek feature films , as the Constellation’s grief-stricken Commodore Matt Decker (guest star William Windom) embarks on a foolhardy quest for revenge against the monster that bested him. (Trek would revisit Herman Melville’s Moby-Dick in Star Trek II: The Wrath of Khan and Star Trek: First Contact .)

The episode still works in a cheesy B-movie sort of way, which some fans would argue is the way it should still be enjoyed. However, when the series was remastered for high definition in the mid-2000s, the decision was made to recreate most of the special effects shots for the series using modern technology, since the originals were never expected to hold up to modern standards. Most of these recreations are very faithful, to the extent that uninitiated viewers might not even realize they’d been replaced. In the case of The Doomsday Machine , however, the producers and effects artists returned to the episode’s original script and attempted to realize writer Norman Spinrad’s initial vision for the space battle sequences. The team at CBS Digital doesn’t sacrifice the overall aesthetic of the series, but they do give us a peek at what The Doomsday Machine — and by extension, the entire Original Series — might have looked like with a feature film budget.  

There may be no better introduction to the character of James T. Kirk than The Corbomite Maneuver . The first episode produced after the series was picked up (though it didn’t air until later in the season), The Corbomite Maneuver finds the Enterprise at the mercy of a massive alien vessel and accused of trespassing in its territory. Unable to outrun or outgun his mysterious adversary, Kirk does what he will later become famous for doing — he cheats. Or, rather, he changes the conditions of the contest from one of technological superiority to one of cunning and guile. In the process, we get to learn a bit about how each of the main characters handles the intense stress of a seemingly hopeless scenario, contrasted against the more relatable Everyman Lt. Bailey (guest star Anthony Call). Though the action rarely leaves the bridge of the Enterprise, it is, in its own way, one of the most thrilling episodes of the series.

Moreover, The Corbomite Maneuver sets the tone for Star Trek as a series. It’s an hour of adventure that is punctuated by moments of thoughtful introspection, warm friendship, and corny jokes. Its depiction of Starfleet and the Enterprise are clearly inspired by military tradition, but the message of the episode is one of compassion and patience rather than conquest. These are scientists, not soldiers, and while they experience fear and doubt, none of their human frailties are a match for their curiosity. If this is what the future of humanity looks like, we want to be a part of it.

When Star Trek is running on full thrusters, it is equal parts silly and profound. In The Devil in the Dark , the Enterprise is sent to the aid of a mining colony where workers are being hunted and killed by an unstoppable monster made of rock. We know that the monster is made of rock because the characters say so; It looks a lot more like it’s made of spray-painted Styrofoam and a shag rug. But as the tension rises and the mystery deepens, the goofiness of the rock monster becomes irrelevant, or even a boon to the story.

Though it begins as a hunt for a merciless alien creature, The Devil in the Dark becomes a story about prejudice and the universality of what we (in our limited earthly experience) would call “basic human rights.” This message is conveyed through cheesy 1960s TV production values and some very hammy acting, but the results are pure and unpretentious, the sort of storytelling that is equally impactful on a jaded adult and a wide-eyed child.

Here in the post-post-postmodern 2020s, we’re all total pros at deconstructing genre tropes. The practice of subverting the audience’s expectations as to what kind of story they’re watching or who the good guys and bad guys are wasn’t new in 1967, either, but in the sci-fi film and television of the era, the big scary monster is usually just a big scary monster. The Devil in the Dark  exemplifies one of Star Trek ’s most enduring themes: that the unknown might seem terrifying, but if you take the time to understand it, it’s actually beautiful.

Star Trek is always science fiction, but its format offers a lot of flexibility in terms of how to interpret that genre. Even within the course of a single series or season, most Star Trek shows alternate between a variety of tones and secondary genres, from grim political drama to steamy romance, or in the case of this episode, kooky workplace comedy. The Trouble with Tribbles pits Captain Kirk and his gallant crew against their most stubborn foe yet — bureaucratic red tape. Assigned to look after a container of grain that Federation administrators insist is gravely important, the Enterprise becomes entangled in a very silly misadventure involving an invasive species of adorable, self-replicating furballs. For a captain accustomed to dealing with high-stakes diplomacy and galactic defense, this is his worst workweek ever.

As lousy a time as Kirk is having, The Trouble with Tribbles is tremendous fun. It is neither the first, nor the last broadly comedic episode of Star Trek , but it is the gold standard by which all Trek comedies are measured. Like any good Trek, it has stakes, a fun science fiction premise, and charming moments of character, but everything is set just a little bit askew, and the characters have noticed. It isn’t parody, it’s situation comedy, only a situation that you’re unlikely to find yourself in unless you’re the crew of a Federation starship. Almost every subsequent Trek series would chase that Trouble with Tribbles heat at least once ( Star Trek: Lower Decks  is basically The Trouble with Tribbles: The Series ), with varying levels of success, but the original remains an untouchable classic.

After The Cage was rejected by NBC, Desilu Studios (under the leadership of comedy queen Lucille Ball herself) took a second swing at the series, with a new cast and a faster paced action-adventure story. This second pilot, Where No Man Has Gone Before , introduces William Shatner as Captain James T. Kirk, as well as George Takei as Lt. Sulu, James Doohan as Scotty, and Leonard Nimoy’s new, more stoic interpretation of science officer Spock.

The episode sees Kirk’s friend and mentee, helmsman Gary Mitchell (guest star Gary Lockwood), bombarded with cosmic radiation that grants him increasingly godlike powers. As Gary grows more dangerous and cruel, Kirk must weigh his love for his friend against his duty to his crew. The scenario immediately establishes the dynamic between Kirk and Spock (compassionate leader versus his coldly practical advisor), though Spock’s regular debate partner, the emotionally driven Dr. McCoy (DeForest Kelley), would not appear until Trek was ordered to series.

Where No Man Has Gone Before  is a little less fun and colorful than the episodes that followed, with a tone more closely resembling heady 1950s sci-fi films like Forbidden Planet or The Day the Earth Stood Still . In a way, it’s the classic Trek episode that feels the most like Star Trek: The Next Generation ; It’s talky, deliberately paced, just a little bit sterile. In Where No Man Has Gone Before , the galaxy is not only wondrous, but also eerie and unsettling. Had this been the tone the series stuck with, it might not have become a global sensation, but as a single episode, it stands out as one of the very best.

To some Trekkies, ranking The City on the Edge of Forever anywhere but at No. 1 is unthinkable. This time travel tale – written by sci-fi author Harlan Ellison and then heavily revised by Trek story editor D.C. Fontana — won Star Trek its first Hugo Award, and is widely considered to be the finest hour in the history of the series, if not the franchise as a whole. The episode’s legendary status is well-deserved, but we don’t quite have the heart to declare it the ultimate Star Trek episode, on account of how little of it takes place in the 23rd century or aboard the Starship Enterprise. The City on the Edge of Forever  is an outlier, and as such, naturally stands apart from the pack, giving it an edge in any conversation about Star Trek . Its placement here at No. 2 is sort of a counter to that advantage.

Make no mistake, however — despite mostly being set in New York in the year 1930, City on the Edge is Star Trek to its core. Sent back in time to correct an accidental alteration of Earth’s history, Kirk and Spock take up residence in a homeless shelter run by idealistic philanthropist Edith Keeler (guest star Joan Collins). Keeler turns out to be the key historical figure whose destiny must be fulfilled, but there’s a problem — Kirk has fallen in love with her. This romance complicates the mission, as Kirk and Spock are confronted with a grave moral dilemma with their entire reality hanging in the balance. Keeler is a visionary who believes in the beautiful future that Kirk calls home. But, in order for that future to exist, must something terrible be allowed to happen in her present? It’s an emotionally gripping tale that, if it had been told on a modern television show, would have changed its characters forever.

Star Trek is built on a central contradiction. It’s an adventure series about officers in a fleet that we are told, unconvincingly, is not a military organization, aboard a vessel that carries enough firepower to demolish a continent. It’s a show about peace in which things have a habit of blowing up. To reconcile this cognitive dissonance, one need only look to this key episode of The Original Series , Balance of Terror . In this early chapter, the Enterprise witnesses an Earth base being destroyed by an old enemy, the Romulan Empire. The Romulan ship has the ability to become invisible both to scanners and the naked eye, and attempts to escape to its own side of the neutral zone between their two territories before it can be apprehended.

The Enterprise is ordered to capture or destroy the Romulans before they make it home. Whether or not they succeed, there may be war. Kirk has his orders, and as we soon discover, so does the Romulan commander (guest star Mark Lenard), who is no happier about this turn of events than Kirk is. Throughout the episode, we cut back and forth between the action on the Enterprise and aboard the Romulan vessel, as two keen military strategists attempt to outmaneuver each other and stay alive, both locked in a struggle they’d rather had never begun.

Balance of Terror is a sci-fi twist on a submarine battle, but more than that, it’s a commentary on war, the rivalries between nations, and the wounds and prejudices they create. The Enterprise isn’t loaded with photon torpedoes because Starfleet is itching for a fight — it’s armed because sometimes it has to be, and when Kirk and his crew ride into battle, there’s nothing glorious about it. On the other side of any conflict is a person or people who have their own mission, their own values, and perhaps even their own reservations about fighting. It is not possible to avoid every fight, to preempt every war with diplomacy. But when blood is shed, there is no victory and there are no winners. There is tragedy, and there are survivors. And, finally, there’s the hope that the next time these two nations clash, they’ll be a little more willing to talk to one another.

It's safe to say The X-Files is one of the most famous and prolific shows in TV history. Running for 11 seasons over 25 years -- and even spawning two theatrically released feature films -- the show was a massive success. And thanks to our modern streaming era, The X-Files continues to live on, being discovered by newcomers and rediscovered by fans who love rewatching their favorite episodes.

While some X-Files episodes receive eternal praise and adoration (like season 3' Clyde Bruckman’s Final Repose and season 5's Bad Blood), others have sadly never gotten their proper dues. If you're an X-Files fan or just anyone who loves sci-fi and a good spooky mystery, check out these underrated episodes that often sit unfairly in the shadows of the more notable ones. 10. Mulder and Scully Meet the Were-Monster (Season 10, Episode 3)

This week marks the 25th anniversary of The Sopranos, one of the all-time great dramas that helped put HBO on the map with its original series. There were HBO shows before The Sopranos, but this is the one that was a breakout hit, and it increased HBO's prestige and standing in the industry. Series creator David Chase had made his name in network television, but no other shows like The Sopranos existed. It was R-rated television in an era before that was a common occurrence.

The Sopranos also made its leading man, the late James Gandolfini, a star for his performance as Tony Soprano, a family man and mob boss who is forced into therapy when his anxiety completely overwhelms him. That set off a six-season run that firmly established The Sopranos' place in TV history. In honor of the show's 25th anniversary, we're sharing our picks for the 10 best episodes of The Sopranos. 10. All Due Respect (Season 5, Episode 13)

Every Star Trek series is someone’s favorite (Star Trek: The Animated Series stans, we see you), but when it comes to the 18-year Golden Age of Trek between 1987 and 2005, the prequel series Enterprise is easily the least beloved. Airing on UPN for an abbreviated four-season run, Enterprise was meant to shake things up after three consecutive series set in the late 24th century. Imagined as a sort of origin story for Star Trek in the style of The Right Stuff, creators Rick Berman and Brannon Braga wanted to capture the danger and excitement of United Earth’s early interstellar space program, even planning to spend the entire first season on Earth preparing for the launch of Starfleet’s very first Starship Enterprise. The network, however, had other ideas, insisting that Berman and Braga not meddle with the consistently successful Star Trek formula. Thus, despite taking place two centuries earlier, Enterprise became, essentially, “more Voyager,” which in turn had been “more Next Generation,” a once-great sci-fi procedural that was nearly a decade past its peak. That’s not to say that the series didn’t improve throughout its four-season run. After two years of struggling to justify the show’s very existence, Berman and Braga swung for the fences with a radically different third season that reinvented Enterprise (now renamed Star Trek: Enterprise) as a grim and gritty serialized drama unpacking the aftermath of a 9/11-scale attack on Earth. While immediately more compelling, the revamp failed to boost the show’s sagging ratings, and it was reworked yet again the following year, and leaned further into the “prequel to Star Trek” angle under new showrunner Manny Coto. This, many fans will argue, is where Enterprise finally found its legs, but it was too little and too late to prevent its cancellation. Still, each iteration of the troubled spinoff had its highlights and our list of the 10 strongest Enterprise episodes is spread fairly evenly throughout the run of the show. Warning: This article contains spoilers for each listed episode.

Star Trek is an American science fiction television series created by Gene Roddenberry that follows the adventures of the starship USS Enterprise and its crew. The show is set in the Milky Way galaxy, roughly during the 2260s. The crew is headed by Captain James T. Kirk, first officer Spock, and chief medical officer Leonard McCoy. Shatner's voice-over introduction during each episode's opening credits stated the starship's purpose: The series was produced from 1966-67 by Desilu Productions, and by Paramount Television from 1968-69. Star Trek aired on NBC from September 8, 1966 to June 3, 1969. Although this television series had the title of Star Trek, it later acquired the retronym of Star Trek: The Original Series to distinguish the show within the media franchise that it began. Star Trek's Nielsen ratings while on NBC were low, and the network canceled it after three seasons and 79 episodes. Nevertheless, the show had a major influence on popular culture and it became a cult classic in broadcast syndication during the 1970s. The show eventually spawned a franchise, consisting of five additional television series, 12 theatrical films, and numerous books, games, toys, and other products.

Star Trek is currently in a bit of a purple patch for content as Paramount Plus , which is the home of all things Star Trek, is responsible for several new shows in recent years. But, it's not just new content, you'll also find where to stream the classics both movies and TV series below. 

Before, Star Trek content was scattered all around different streaming services and searching for what you wanted to watch could feel like hunting for a cloaked Bird of Prey. However, these days you're able to stream all Star Trek content out there on Paramount Plus. However, we do have round-ups of the best sci-fi movies and TV shows on Netflix , Disney Plus and Amazon if you want to check them out. 

You can also check out our take on the Star Trek movies, ranked so you know which movies to beam up onto your device. While Paramount Plus has everything Star Trek out there, you can find the odd bit of content on other platforms. So, below you'll find where you can watch what, regardless of where you're based, in our Star Trek streaming guide.  

The Star Trek movies can be divided into three tidy groups: the original cast, the Next Generation cast, and the reboot cast. All of them can be found on Paramount+. However, Paramount+ isn't the only place you can stream the movies and in some cases you can rent or buy from places such as Amazon .

Here’s how to stream the Star Trek movies in the U.S., in order of release:

Star Trek: The Motion Picture — Paramount+ Star Trek II: The Wrath of Khan — Paramount+ Star Trek III: The Search for Spock — Paramount+ Star Trek IV: The Voyage Home — Paramount+ Star Trek V: The Final Frontier — Paramount+ Star Trek VI: The Undiscovered Country — Paramount+ Star Trek: Generations — Paramount+ Star Trek: First Contact — Paramount+ Star Trek: Insurrection — Paramount+ , Spectrum Star Trek: Nemesis — Paramount+   Star Trek (2009) — Paramount+ , Pluto TV Star Trek Into Darkness — Paramount+ , Pluto TV Star Trek Beyond — Paramount+ , DIRECTV , Freevee

When it comes to Star Trek on the small screen, you can find them all in one place. Paramount+ not only has every episode of every legacy Trek show, it’s also the home of all the new Star Trek programming, such as Picard and Strange New Worlds. If you’re a Trekkie, you absolutely want to have Paramount+ to keep up with the object of your affection. A word of warning though, other streaming platforms may only have select episodes or series to stream.

Star Trek: The Original Series — Paramount+ , Pluto TV Star Trek: The Next Generation — Paramount+ , Pluto TV Star Trek: Deep Space Nine  — Paramount+ , Sling , Spectrum Star Trek: Voyager — Paramount+ , Pluto TV Star Trek: Enterprise — Paramount+ Star Trek: Discovery — Paramount+ , DIRECTV Star Trek: Picard — Paramount+ Star Trek: Short Treks — Paramount+ Star Trek: Lower Decks — Paramount+ Star Trek: Prodigy — Paramount+ ,   DIRECTV , FuboTV , Spectrum Star Trek: The Animated Series — Paramount+ Star Trek: Strange New Worlds — Paramount+

Now that Paramount+ has arrived in the U.K, streaming Star Trek is a lot easier. You can view most of the movies on the streaming platform. Star Trek Beyond is the exception but that can be found on Amazon Prime. If you're not prepared to subscribe to Paramount+, the movies are available to rent or buy from a number of different platforms. 

Star Trek: The Motion Picture — Paramount+ Star Trek II: The Wrath of Khan — Paramount+ Star Trek III: The Search for Spock — Paramount+ Star Trek IV: The Voyage Home — Paramount+ Star Trek V: The Final Frontier — Paramount+ Star Trek VI: The Undiscovered Country — Paramount+ Star Trek: Generations — Paramount+ Star Trek: First Contact — Paramount+ Star Trek: Insurrection — Paramount+ Star Trek: Nemesis — Paramount+ Star Trek (2009) — Paramount+ , Amazon Prime Star Trek Into Darkness — Paramount+ , Amazon Prime Star Trek Beyond — Amazon Prime

Now that Paramount+ has reached those across the pond, the U.K. can enjoy streaming Star Trek shows as well. Netflix is also another great option to fulfil your Trekkie viewing needs, especially if you're interested in checking out Star Trek: The Animated Series, which is exclusive to Netflix. 

However, for the likes of Picard and Lower Decks, you’ll have to hop on over to Amazon Prime. It's worth noting that platforms such as SkyGo may only have a select number of episodes or series to stream.
