My Cousin Rachel is a 1952 American romantic mystery film directed by Henry Koster and starring Olivia de Havilland, Richard Burton, Audrey Dalton, Ronald Squire, George Dolenz and John Sutton. The film is based on the 1951 novel of the same name by Daphne du Maurier.

Twentieth Century-Fox obtained the rights to film the novel, with Burton's agreeing to star in a U.S. film for the first time. Production was troubled when du Maurier and original director George Cukor were dissatisfied with the adaptation, causing Cukor to leave the project.

My Cousin Rachel received some positive reviews upon its initial release, including for Burton's performance. It was nominated for four Academy Awards, and Burton won a Golden Globe for New Star of the Year.

The story was remade My Cousin Rachel in 2017 starring Rachel Weisz and Sam Claflin.
