SG-1's conclusion
2008After season 10, SG-1 wraps up with two TV movies that close out its big storylines: first the Ori crusade, then a leap through time.
Atlantis, on its own
2007 to 2009Atlantis carries on alone in Pegasus for two final seasons.
Stargate Universe
2009 to 2011A new era, darker and more intimate, aboard the Ancient ship Destiny, lost at the far edge of the universe.
On the side
Prequel & non-canonOrigins (2018) is a short prequel about young Catherine Langford: watch it whenever you like. As for the animated series Infinity, it's non-canon and disowned by its own creators.
Frequently asked questions
What order should I watch Stargate in?
Start with Stargate SG-1. Then begin Atlantis around the end of SG-1 season 7 or during season 8, since the two shows run in parallel and cross over. Finish with Universe, and slot the movies in after SG-1.
Airing order or chronological order?
Airing order is the simplest, and the most faithful to the experience the creators intended. A strict episode-by-episode chronological order does exist, but it makes watching more complicated for very little payoff.
Can I watch SG-1 and Atlantis at the same time?
Yes, it's actually recommended. The two shows share characters and events: following them in parallel at the right moment makes the crossovers far more rewarding.
Where do the movies fit in?
The Ark of Truth and Continuum come after SG-1 season 10, picking up where its story left off. The 1994 movie can be watched before everything else, or skipped altogether: you don't need it to follow the series.
Original US episode titles. This order follows the original broadcast. Strictly chronological, episode-by-episode orders exist too, but watching the seasons in parallel remains the simplest and most faithful way to experience the saga.
