This is a list of Star Trek: The Original Series episodes, in production order, with original NBC air dates. NBC aired the episodes out of order, therefore the first episode of the series actually broadcast was The Man Trap while the second pilot, Where No Man Has Gone Before was, somewhat confusingly for viewers, aired third.

Some television syndication packages include a retrospective, Star Trek Memories hosted by Leonard Nimoy, which was produced prior to the release of Star Trek III: The Search for Spock, as an 80th episode. "The Cage" is usually distributed separately from the rest of the series for broadcast purposes.
