No Man of Her Own is a 1950 American film noir drama directed by Mitchell Leisen and featuring Barbara Stanwyck, John Lund, Phyllis Thaxter, Jane Cowl and Lyle Bettger. The production is the second film Stanwyck made with director Mitchell Leisen, and its screenplay was adapted from Cornell Woolrich's 1948 novel I Married a Dead Man. Woolrich is cited in the film's opening credits by one of his commonly used pseudonyms, "William Irish". Plot Helen Ferguson, filled with dread, holds her baby as Bill Harkness reads a book. The phone rings, and police tell Bill that they are on the way to their home. She puts the child to bed, praying that the boy will not suffer for her mistakes and whispering that she was desperate.

With a better life provided for her son, Helen continues the ruse while Bill Harkness, who is the elder brother of the deceased Hugh, falls in love with her. Helen's ex-boyfriend, the father of her child, tracks her down several months after the accident.
