Top Ten Star Trek: The Original Series Episodes

The most intriguing episodes of the original series.

The Top Ten

1 City on the Edge of Forever

Edith Keeler must die.

This one is a memorable episode with a spin on society in a Earthly city and their own understanding of it where coming from a future very different. On the other hand it is close to home and one might believe it is just too easy to go so close to home. Has a charm and possible why it is at the top placement seeming 2018 it is captivating but there might be that other drawback. - iliescu

This is one of my favorite episodes of Star Trek. Number one because William Shatner is hot and I love him, and I love the romance in this. 1930 is one of my favorite centuries. All the great movies and defiantly the shows. Kirk is defiantly great in this show. Please rate this top one Thanks!

Kirk, Spock, and Bones find a portal through time and end up in the 1930's where Kirk falls for Joan Collins and must let her die in order to save earth from the Nazis.

2 The Trouble with Tribbles

A light-hearted episode with the extremely cute, continuously pregnant creatures known as tribbles.

3 Mirror Mirror

Spock should have kept the beard... makes him look better and gave him a more "evil" Vulcan look as well... plus Marlena Moreau (Barbara Luna) has lived in my fantasies since I first saw this episode when I was 8... LOL

Downright exciting episode, although as usual, Scotty (James Doohan) overplays his character. - CrazyElephant

The Enterprise encounters an evil version of itself in a parallel universe. Spock sports a goatee - a symbol that continues to be used in media today to different the good version from evil when a copy exists.

This episode. Period. I mean it was an alternate universe, hello?

I think its just me, but when the transporter got fixed and Kirkk returned to the normal universe, when I saw Spock's beard gone, I found it odd and unfamiliar. I donna know why.

4 Amok Time

Spock is driven by Vulcan biology to find his mate on his home planet or die. He ends up having to fight Kirk and "kills" him.

WOW all these were good episodes! I like this one because Spock can't control what he has to do. - beckihrh

5 Arena

Gorn: Slither snort sneer
Kirk: I got them gunpowder.

6 Space Seed

This episode works on a couple levels but the writers must have thought there was something more there since they made a movie from the original premise. - mgenet

The enterprise discovers genetically altered superhumans and Kirk encounters his nemesis Khan (the inimitable Ricardo Montalban).

7 Dagger of the Mind

Dr adams lol

8 The Doomsday Machine

Matt decker beamed his crew down to the third planet, "matt there is no THIRD PLANET ' matt " don't you think I know that, there was but not anymore". Decker takes command, spock follows orders, Kirk at his best... And the music, the battle music... Enough said.

9 I, Mudd

Classic scene. Very humorous

10 The Enemy Within

A malfunction on the transporter causes Kirk to split into 2 parts - one gentle and one aggressive.

This is true acting a great prevormance

The Contenders

11 Operation - Annihilate!

The stakes are very high - and then they get even higher when things get personal! The triumvirate are at their best and most professional

12 The Menagerie

A 2 part episode involving scenes from the original unaired pilot with the original Captain Pike and the famous dancing green girl.

13 The Squire of Gothos

A remote planet has a sentient being that might be in manipulation of another group of entities as one or a supercomputer. The intrigue is the Enterprise ship finds its way to it and the Captain has then discussions and shares in debates with the being and the name is Tremane. It is smart and with wit but the observer decides. - iliescu

Tremane outdoes himself in this home base offensive from the Enterprise to the Magic Castle of the Squire. A little old fashion but the musical taste and talent are still present. One of the favorite Star Trek episodes of all time other than 'The City on The Edge of Forever' it is just simple and a glimpse that sometimes the past is beautiful to remember. Tremane also can duel Kirk with old fashion pistols, Kirk wins it since the Mirror of Tremane gets shot and his machine is then in reveal. Plus the godly parents call Tremane to not pursue Kirk further which shows there might always be a greater advantage despite the high class Tremane appears to be a part of. Real intelligent and yes maybe Uhura can play the music instrument some time unless it is sarcasm. Uncertain a little difficult to figure out. Amazing way to see things through with this Episode with much to contemplate old and new, past and future. Excellent job and music taste Tremane! - iliescu

Tremane for some reason is also better than Captain Kirk which is shown on the Card Game of the Original Series - Star Trek. Their attack is both a numeral of 7, in Communications Kirk has a 4, Tremane has a 5. As for Science, Kirk has a 4 and Tremane has 5. Luck on Kirk side, the Guardians of Tremane removed him despite please for more time to spend with the Captain otherwise. - iliescu

14 In a Wink of an Eye

Beings that move faster than the speed of light. Kirk is shown pulling his pants on in the bedroom of a woman while she brushes her hair in a negligee.

15 Errand of Mercy

Inspirational for Stargate's episode "The Nox" which is about 90% the same plot.

John Colicos was the ultimate Klingon in this episode. The looks on the faces of the old Organians was absolutely priceless while Kirk and Spock desperately try to muddle through a Klingon occupation and Organian indifference. - Rilonor

16 Balance of Terror

One of the best combat episodes of any series. With the Enterprise and the Romulans playing cat and mouse, it reminded me of the old WWII submarine movies. - odog502

Based on WW2 submarine movies

17 Plato's Stepchildren

The infamous episode where Kirk and Uhura are forced to kiss at the hands of powerful beings.

18 Turnabout Intruder

Kirk's consciousness gets trapped in a woman intent on taking over command. In this series, women weren't allowed to be captains.

19 The Enterprise Incident
20 The Devil in the Dark

This one of the best episodes of the original series. Monster, terror, and mystery. What else could one want? It is gratifying that Kirk, the man of action, can stop, remember who and what he is, and help a poor alien creature that resorts to violence to protect her children. Nimoy's and Shatner's performances were spectacular! - Rilonor

21 A Piece of the Action
22 Shore Leave

Lots of fun. It has everything: Great music, great location shooting, great performances and a guy in a giant rabbit suit.

23 The Gamesters of Triskelion

Very good episode, Angelique Pettyjohn (I miss you, Shana! You died too soon! ) plays her role so divinely... this episode is my favorite, along with "Mirror Mirror" and "Where No Man Has Gone Before. "

24 Journey to Babel
25 The Galileo Seven

Full of excitement and entertainment good story all round

26 Spock's Brain

Absolutely awful. One would think that Ed Wood wrote this one. Yikes! with a capital ikes! - Rilonor

27 The Tholian Web
28 The Man Trap
