Marvel's Agent Carter, or simply Agent Carter, is an American television series created by Christopher Markus & Stephen McFeely for ABC, based on the Marvel Comics character Peggy Carter following her roles in the 2011 film Captain America: The First Avenger and the 2013 Marvel One-Shot short film of Agent Carter. It is set in the Marvel Cinematic Universe (MCU) and shares continuity with the franchise's films and other television series. The series was produced by ABC Studios, Marvel Television, and Fazekas & Butters, with Tara Butters, Michele Fazekas, and Chris Dingess serving as showrunners.

Hayley Atwell reprises her role of Peggy Carter from the film series and One-Shot, with James D'Arcy, Chad Michael Murray, and Enver Gjokaj also starring; they are joined by Shea Whigham for the first season. In the series, Carter must balance life as a secret agent with that of a single woman in 1940s America. Development on a series inspired by the short film had begun by September 2013, with Atwell's involvement confirmed in January 2014. That May, ABC ordered the show straight to series. Agent Carter introduces the origins of several characters and story lines from MCU films, while other characters from the films also appear.

The first season, consisting of eight episodes, originally aired from January 6 to February 24, 2015, while the second season, consisting of 10 episodes, originally aired from January 19 to March 1, 2016. Both seasons aired during mid-season breaks of Agents of S.H.I.E.L.D. Despite a positive critical response, viewership fell, and on May 12, 2016, ABC cancelled Agent Carter.
