Lady in the Dark is a 1944 American musical film directed by Mitchell Leisen, from a screenplay by Frances Goodrich and Albert Hackett that is based on the 1941 musical of the same name by Moss Hart. The film stars Ginger Rogers as a magazine editor, who although successful, finds herself on the edge of a breakdown while juggling her feelings for three prospective suitors, played by Ray Milland, Warner Baxter, and Jon Hall.

Paramount won the screen rights to the musical in February 1941, after a bidding war with Columbia, Warner Bros., and Howard Hughes. The studio initially purchased the property as a vehicle to reunite Rogers with Fred Astaire. However, after negotiations with Astaire failed, the studio cast Milland, who had recently starred with Rogers in Paramount's The Major and the Minor.

The film was first released on February 10, 1944, and was a critical and commercial success. It was nominated for three Academy Awards; for Best Cinematography, Best Music, and Best Art Direction (Hans Dreier, Raoul Pene Du Bois, Ray Moyer).
