Top 100 Star Trek Episodes Of All Time

The Top 100 Star Trek Episodes Of All Time!

Star Trek gave us six TV series, spanning over 700 episodes, because it’s such a rich universe. And a Federation starship is the perfect vehicle to tell unforgettable stories. But which Star Trek stories are the best? To find out, we painstakingly compiled the 100 greatest Trek episodes, from any of the series.

What makes for a great Star Trek episode? Obviously, the fun quotient has to be high, and there need to be awesome character moments. But I’d argue that a really notable Trek story explores some ideas, or some ethical quandaries, in a way that sticks with you after you’re done watching. If one thing has defined Trek throughout its run, it’s that.

So here’s our list of the 100 best Star Trek episodes. Please let us know which episodes we missed, or ranked incorrectly!

Warning: some spoilers below, although we try not to give away all the plot twists.
