Dr. Elizabeth Weir is a fictional character in the Canadian-American Sci-Fi Channel television series Stargate Atlantis, a military science fiction show about a military team exploring another galaxy via a network of alien transportation devices. Elizabeth Weir is introduced as a recurring character in the Stargate SG-1 season seven two-parter, Lost City. She does not hold any military rank since she is a civilian. Weir is the leader of the Atlantis expedition in Stargate Atlantis until the last episode of season three, titled "First Strike".
The character was primarily played by Torri Higginson, although when introduced in the Stargate SG-1 two-parter Lost City, she was played by Jessica Steen. In the season 5 Atlantis episode "Ghost in the Machine", the consciousness of Elizabeth Weir, having been transferred to sub-space by a group of Replicators hoping to ascend, was transferred to a Replicator template and portrayed by Michelle Morgan.
