Gloria Grahame (November 28, 1923 – October 5, 1981) was an American actress.

Grahame began her acting career in theatre, and in 1944 she made her first film for MGM. Despite a featured role in It's a Wonderful Life (1946), MGM did not believe she had the potential for major success, and sold her contract to RKO Studios. Often cast in film noir projects, Grahame received a nomination for an Academy Award for Best Supporting Actress for Crossfire (1947), and she won this award for her work in The Bad and the Beautiful (1952). She achieved her highest profile with Sudden Fear (1952), Human Desire (1953),The Big Heat (1953), and Oklahoma! (1955), but her film career began to wane soon afterwards.

She returned to work on the stage, but continued to appear in films and television productions, usually in supporting roles. Diagnosed with stomach cancer in 1980, Grahame refused to accept the diagnosis and travelled to England to work in a play. Her health rapidly failed and she returned to New York City, where she died in 1981.
