Watch List: Only Stargate SG-1’s Key Episodes

Lots of new viewers are joining the Stargate family every day! But maybe you aren’t quite ready for a months-long binge of all 214 episodes of Stargate SG-1.

That’s where this list comes in. We’re breaking out a list of only the most important episodes from the show’s ten seasons and two movies. (It was tough, but we managed to whittle it down to 107 episodes.) Watch these and you’ll get everything you need for the major ongoing storylines, as SG-1 explores the galaxy and fights to protect Earth and its allies from alien threats that span three galaxies.

Stargate SG-1 premiered in 1997, when TV shows were more episodic — with more stand-alone episodes loosely connected by ongoing storylines. So of course we recommend watching more than the episodes on this list to really get the best of SG-1. Many of the show’s finest hours are not part of the main story arcs. (Pro Tip: Look through the season-by-season episode guides to find other episodes rated 3 stars and higher.)

    • Stargate Atlantis starts a little slow, like SG1 kinda did in season 1. But the tail end of S1 it gets better and in S2 you get Ronan Dex (Jason Momoa)) and it’s all uphill from there.
      It’s a good cast they have once he joins. You get all the chewy cracks, bad a$$ fight scenes and Ronan & the scientists comical relationship.
      > I tried watching SG1 and Atlantis a few times and couldn’t get into them, I’m very thankful I stuck it out in long run. Have binged both series 2-3 times over the years.

  • Several of the episodes are wrongly numbered. Eg: The Tok'Ra episodes are S02 E11-12, not E10-11 like this guide says.

  • Great List! I will use it to watch the key episodes. I noticed you did include the two cassandra episodes from season 2, but not the two cassandra epidsodes "Singularity" (season 1) and "Rite of Passage" (season 5). So I would add them for my list :-)

    • Yep, those episodes would be good for filling out who the Cassandra character is (and how nasty Nirrti is!). I left her story aside as nonessential, and included the other episodes with Cassandra in them for other reasons.

  • Hello, are there any essential episodes of SG-1 for someone watching Atlantis when it enters the series that are not included in this list?

    • Good question, Dylan! We still need to assemble our Atlantis Key Episodes list. But for someone watching Atlantis but not SG-1, who wants SG-1 episodes that reference or inform developments on Atlantis, offhand I can think of these:

      "Lost City" (721-722)
      "New Order" (801-802 ... both 2-parters precede the Atlantis premiere)
      "Prometheus Unbound" (812 ... not essential, but fun)
      "It's Good to Be King" (813)
      "Moebius" (819-820 ... right before SGA's "The Siege, Part 2")
      "The Pegasus Project" (1003)

      There are a handful of other references in SG-1, but they are very casual ("Hey, I want to go to Atlantis!" "We got this info from Atlantis," etc.)

  • this list is missing the episode that introduces the trust and the episodes with the evolved human research exploration (probly not neccicary but i like them) other than that great list

  • S03 E05 "Learning Curve" should be on the watch list, SGC gets a naquadah generator prototype.

  • Really appreciate you taking the time to do this. I only ever watched the original film until I saw it pop up on Netflix. Wasn't about to watch every single episode. Sadly, SG1 leaves Netflix today (in USA at least), so I'll need to grab the last two seasons from my local library. Now to give Atlantis a try too!

  • You left out S1-15 "singularity" which introduces Cassandra who appears in S2-2 "in the line of duty", that you included in S2's key episodes.
