Sharon Carter is a character appearing in American comic books published by Marvel Comics. Created by Stan Lee, Jack Kirby, and Dick Ayers, the character first appeared in Tales of Suspense #75. Sharon Carter is a secret agent and an ex-field agent of S.H.I.E.L.D. under Nick Fury. She is also a love interest of the superhero Captain America / Steve Rogers. Sharon Carter was originally the younger sister of Peggy Carter. She was later retconned as Peggy's grand-niece because of the unaging nature of comic book characters.

Tales of Suspense is the name of an American comic book anthology series, and two one-shot comics, all published by Marvel Comics. The first, which ran from 1959 to 1968, began as a science-fiction anthology that served as a showcase for such artists as Jack Kirby, Steve Ditko, and Don Heck, then featured superheroes Captain America and Iron Man during the Silver Age of Comic Books before changing its title to Captain America with issue #100. Its sister title was Tales to Astonish. Following the launch of Marvel Legacy in 2017, Tales of Suspense was once again resurrected at issue #100, featuring the Winter Soldier and Hawkeye in a story called "The Red Ledger".
