None but the Lonely Heart is a 1944 American drama romance film which tells the story of a young Cockney drifter who returns home with no ambitions but finds that his family needs him. Adapted by Clifford Odets from the 1943 novel of the same title by Richard Llewellyn and directed by Odets, the film stars Cary Grant, Ethel Barrymore, and Barry Fitzgerald.

The title of the film is taken from Tchaikovsky's song "None but the Lonely Heart", which is featured in the background music.
