Four Daughters is a 1938 American romance film that tells the story of a happy musical family whose lives and loves are disrupted by the arrival of a charming young composer who interjects himself into the daughters' romantic lives. His cynical, bitter musician friend comes to help orchestrate his latest composition and complicates matters even more. The movie stars the Lane Sisters (Priscilla Lane, Rosemary Lane, and Lola Lane) and Gale Page, and features Claude Rains, Jeffrey Lynn, John Garfield, and Dick Foran. The three Lanes were sisters and members of a family singing trio.

The film was written by Lenore J. Coffee and Julius J. Epstein, adapted from the 1937 Fannie Hurst story "Sister Act", and was directed by Michael Curtiz. The movie's success led to two sequels with more or less the same cast: Four Wives and Four Mothers. The same cast—with the addition of Fay Bainter and Donald Crisp—appeared in the film Daughters Courageous, which had no connection with the Lemp family trilogy.
