Samantha "Sam" Carter, USAF is a fictional character in the Canadian–American military science fiction Stargate franchise. Played by Amanda Tapping, she appears in all three shows in the franchise: Stargate SG-1, Stargate Atlantis, and Stargate Universe. She was a main character in all ten seasons of Stargate SG-1 (1997–2007). Following a recurring role in Stargate Atlantis for three seasons (2004–07), Carter became a main character in Season 4 of Atlantis (2007–08), and also appeared in the 2008 direct-to-DVD SG-1 films Stargate: The Ark of Truth and Stargate: Continuum. Amanda Tapping accepted a starring role in Sanctuary and appears in only the first and last episodes in Season 5 of Atlantis (2008–09). Carter also appears in two episodes of Season 1 of Stargate Universe.

Captain Samantha Carter made her first appearance in "Children of the Gods", the pilot episode of Stargate SG-1, as a United States Air Force Captain who joined the fictional SG-1 team under the command of Colonel Jack O'Neill. After being promoted to Major in Season 3, Carter remained O'Neill's second-in-command until her promotion to Lieutenant-Colonel early in Season 8, at which point she assumed command of the SG-1 team and O'Neill was promoted to Brigadier-General in order to lead Stargate Command. Between Seasons 8 and 9 of SG-1, following the defeat of the Replicators and downfall of the Goa'uld system lords, she accepted a position as Head of the Stargate Research and Development Programme, based in Nevada. At the time of the emergence of the Ori, she was engaged in deep-space research but was reassigned to SG-1, now under the command of Lieutenant Colonel Cameron Mitchell, on her return to Earth. Following the defeat of the Ori in Stargate: The Ark of Truth, Carter was promoted to a "full bird" Colonel and appointed as the new commander of the Atlantis expedition early in Season 4 of Atlantis. Later, Carter is given command of the Daedalus-class ship, the George Hammond.
