What’s on the Stargate Episode Timeline?
This Stargate episode timeline includes all of the episodes from the three Stargate shows, including SG-1, Atlantis, and Universe. This timeline also includes the 1994 film that launched this story. The timeline does not include any of the comics, books, video games, or the animated Stargate series, since those works are considered largely non-canonical, and therefore not relavant to this timeline.
As with our other timelines, don’t forget to let us know if there’s something that needs changing, whether it be adding, taking away, or rearranging pieces of this timeline. Thank you, and we hope you enjoy.
