Gentleman's Agreement is a 1947 American drama film based on Laura Z. Hobson's best-selling 1947 novel of the same title. The film is about a journalist (played by Gregory Peck) who pretends to be Jewish to research an exposé on the widespread antisemitism in New York City and the affluent communities of New Canaan and Darien, Connecticut. It was nominated for eight Academy Awards and won three: Best Picture, Best Supporting Actress (Celeste Holm), and Best Director (Elia Kazan).

The movie was controversial in its day, as was a similar film on the same subject, Crossfire, which was released the same year (though that film was originally a story about anti-homosexuality, later changed to antisemitism).

In 2017, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
