The Red House is a 1947 American psychological horror film noir directed by Delmer Daves and starring Edward G. Robinson, Lon McCallister, Judith Anderson, Rory Calhoun, Allene Roberts, and Julie London. Its plot follows a young woman raised by a brother and sister who are concealing a secret involving an abandoned farmhouse located deep in the woods on their sprawling property. It is based on the 1945 novel of the same name by George Agnew Chamberlain, which was popularly serialized in The Saturday Evening Post. The screenplay was adapted by Daves and Albert Maltz, the latter uncredited. It marked actress Ona Munson's last feature film appearance.

Principal photography of The Red House took place in the spring of 1946, largely in Sonora, California. The film was released theatrically through United Artists, with an early premiere taking place at the Plaza Theatre in Palm Springs on December 30, 1946, before it was widely distributed on February 7, 1947. It received largely favorable reviews from film critics.

Retrospective assessment of the film has noted its genre-defying elements, surreal musical score, and provocative themes. In 2019, Paste magazine declared The Red House the best horror film released in 1947.
