List of Stargate Atlantis episodes

The fourth season of Stargate Atlantis, an American-Canadian television series, began airing on September 28, 2007 on the US-American Sci Fi Channel. The fourth season concluded after 20 episodes on March 7, 2008 on Sci Fi. The series was developed by Brad Wright and Robert C. Cooper, who also served as executive producers. Amanda Tapping (Col. Samantha Carter) joins the cast as a regular for 14 episodes, Jewel Staite (Dr. Jennifer Keller) was a recurring character for eleven episodes, while regular cast member Torri Higginson (Dr. Elizabeth Weir) was a recurring cast member for four episodes. Other season four regular cast members include Joe Flanigan, David Hewlett, Rachel Luttrell and Jason Momoa.

Episodes in bold are continuous episodes, where the story spans over 2 or more episodes.

With the season premier, "Adrift", Amanda Tapping replaces Torri Higginson in the opening credits sequence, with Paul McGillion no longer appearing. This marks Amanda Tapping's first appearance as a main character on Atlantis. It also marks the only time an actor has appeared in the opening credits of both Stargate SG-1 and Atlantis. Christopher Judge has a cameo appearance as his Stargate SG-1 character Teal'c in "Reunion" and guest stars in the episode "Midway". Judge is the last original Stargate SG-1 regular to appear on Atlantis, as the other three characters in the original SG-1 team all appeared in Atlantis's first season, as did other SG-1 characters Hank Landry and George Hammond. Of the three other SG-1 regulars (namely Cam Mitchell, Vala Mal Doran and Jonas Quinn), Mitchell and Vala visited Atlantis in the SG-1 crossover episode "The Pegasus Project". Jodelle Ferland, who plays Princess Harmony in the episode "Harmony", previously appeared in the episode "Flesh and Blood" in Stargate SG-1 season 10 as a young Adria; and Crystal Lowe previously appeared in the episode "Emancipation" in season 1 of Stargate SG-1.
