Star Trek’s 45th Anniversary – The 10 Best Episodes

Star Trek’s 45th Anniversary – The 10 Best Episodes

Forty-five years ago today, Star Trek premiered on NBC. Seventy-nine episodes, an animated series, eleven movies, and four spin-off series later; the little show that NBC cancelled after three seasons has become a cornerstone of science fiction. What better occasion to list the ten best episodes of the Original Series?

All of these episodes are available for online streaming on Just in case you’ve never seen one of them, I included a link to the episode.

The City on the Edge of Forever

I doubt anyone would disagree that this is the best episode of the Original Series, and possibly of all Trek. This is the one where McCoy, while tripping out on drugs, runs through the Guardian of Forever and prevents Joan Collins from being killed, which prevents America from entering WWII due to her pacifist activism. So Kirk has to go back in time, fall in love with her, and then watch her get hit by a truck. Watch this episode on the official site.

Mirror, Mirror

Spock has a goatee! Admit it, when you saw that for the first time; you thought it was the coolest thing ever. Kirk gets tossed into an alternate universe where the Federation is a warlike empire and manages to get to the Spock of that universe, who we later learn in DS9 was able to change things. Watch this episode on the official site.

Space Seed

Khaaaaaaaaaaaan! This little episode, where the Enterprise finds genetically engineered supermen frozen in stasis would lead to the best Star Trek movie ever made. If you haven’t seen it, watch this episode on the official site.

The Trouble With Tribbles

This is perhaps one of the most famous of all Original Series episodes. It’s lighthearted, and a lot of fun. They even chose this episode to revisit when on Deep Space Nine they wanted to include that crew in an Original Series episode. Watch this episode on the official site.
