Marnie is a 1964 American psychological thriller film directed by Alfred Hitchcock from a screenplay by Jay Presson Allen, based on the 1961 novel of the same name by Winston Graham. The film stars Tippi Hedren and Sean Connery.

Marnie became a milestone for several reasons. It was the last time a "Hitchcock blonde" would have a central role in one of his films. It also marked the end of Hitchcock's collaborations with cinematographer Robert Burks, who died in 1968; editor George Tomasini, who died soon after Marnie's release; and composer Bernard Herrmann, who was fired during Hitchcock's next film, Torn Curtain (1966), when Hitchcock and Universal studio executives wanted a pop-and-jazz-influenced score for the film.
