Whirlpool is a 1950 American film noir thriller directed by Otto Preminger and written by Ben Hecht and Andrew Solt, adapted from the 1946 novel Methinks the Lady... by Guy Endore. The film stars Gene Tierney, Richard Conte, José Ferrer and Charles Bickford, and features Constance Collier in her final film role. Its plot follows the kleptomaniac wife of a wealthy Los Angeles psychoanalyst who, after a chance meeting with a hypnotist, is charged with a violent murder.

Owing to anti-British statements screenwriter Hecht had made in the recent past concerning the United Kingdom's involvement in Israel, prints of the film initially circulated in the country replaced his credit with the pseudonym Lester Barstow.
