This is a list of Star Trek Online episodes and the episode or storyline missions.
There are four series of episodes: the Federation series, the Klingon series, the Romulan Republic series and the Featured series.
The Federation series and the Klingon series are made available to play when the character reaches a certain rank. Both series are repeatable.
The featured series (called featured episodes by the Star Trek Online community) are available only for a brief period of time, usually a month. Yet, the missions have been incorporated as part of the Federation or Klingon series by Cryptic Studios in future updates, making them available for players to replay them. This series are experienced the same by both Federation characters and Klingon Empire characters.
