A Girl of Yesterday is a 1915 American silent comedy film directed by Allan Dwan, and distributed by Paramount Pictures and Famous Players-Lasky. The film starred Mary Pickford (who also wrote the scenario) as an older woman. Before this film, Pickford was mainly cast in "little girl" roles which were popular with the public. The picture costarred Pickford's younger brother Jack, Marshall Neilan, Donald Crisp, and Frances Marion, who later became a prolific screenwriter. Real life aviation pioneer Glenn L. Martin also made a cameo in the film.
