Two-Faced Woman is a 1941 American romantic comedy film directed by George Cukor and starring Greta Garbo in her final film role, Melvyn Douglas, Constance Bennett, and Roland Young. The movie was distributed by Metro-Goldwyn-Mayer.

Garbo plays a wife who pretends to be her own fictitious twin sister in order to recapture the affections of her estranged husband (Douglas), who has left her for a former girlfriend (Bennett). The film is generally regarded as the box-office flop that ended Garbo's career in an unsuccessful attempt to modernize or "Americanize" her image in order to increase her shrinking fan base in the United States. By mutual agreement, Garbo's contract with MGM was terminated shortly after Two-Faced Woman was released, and it became her last film.
