The Long Voyage Home is a 1940 American drama film directed by John Ford. It stars John Wayne, Thomas Mitchell and Ian Hunter. It features Barry Fitzgerald, Wilfrid Lawson, John Qualen, Mildred Natwick, and Ward Bond, among others.

The film was adapted by Dudley Nichols from the plays The Moon of the Caribbees, In the Zone, Bound East for Cardiff, and The Long Voyage Home by Eugene O'Neill. The original plays by Eugene O'Neill were written around the time of World War I and were among his earlier plays. Ford set the story for the motion picture, however, during the early days of World War II.

While not one of Ford's best-known works, The Long Voyage Home continues to be well received. Film critics and scholars have noted Gregg Toland's distinctive cinematography, which serves as a precursor of the film noir aesthetic and hinted at his work for Orson Welles' film Citizen Kane (1941).
