Jamaica Inn is a 1939 British adventure thriller film directed by Alfred Hitchcock and adapted from Daphne du Maurier's 1936 novel of the same name. It is the first of three of du Maurier's works that Hitchcock adapted (the others were her novel Rebecca and short story "The Birds"). It stars Charles Laughton and Maureen O'Hara in her first major screen role. It is the last film Hitchcock made in the United Kingdom before he moved to the United States.

The film is a period piece set in Cornwall in 1820, in the real Jamaica Inn (which still exists) on the edge of Bodmin Moor.
