The Three Faces of Eve is a 1957 American drama film presented in CinemaScope, based on the book of the same name about the life of Chris Costner Sizemore, which was written by psychiatrists Corbett H. Thigpen and Hervey M. Cleckley, who also helped write the screenplay. Sizemore, referred to by Thigpen and Cleckley as Eve White, was a woman they suggested might have dissociative identity disorder (then known as multiple personality disorder). Sizemore's identity was concealed in interviews about this film and was not revealed to the public until 1977. The film was directed by Nunnally Johnson.

Joanne Woodward won the Academy Award for Best Actress, making her the first actress to win an Oscar for portraying three personalities (Eve White, Eve Black, and Jane). The Three Faces of Eve also became the first film since 1936—when Bette Davis won for Dangerous (1935)—to win the Best Actress award without getting nominated in any other category.
