Bluebeard's Eighth Wife is a 1938 Paramount Pictures American romantic comedy film directed and produced by Ernst Lubitsch and starring Claudette Colbert and Gary Cooper. The film is based on the 1921 French play La huitième femme de Barbe-Bleue by Alfred Savoir and the English translation of the play by Charlton Andrews. The screenplay was the first of many collaborations between Charles Brackett and Billy Wilder. The film is a remake of the 1923 silent version directed by Sam Wood and starring Gloria Swanson.

Émilie Chauchoin, professionally known as Claudette Colbert, was an American actress. Colbert began her career in Broadway productions during the late 1920s and progressed to films with the advent of talking pictures. Initially contracted to Paramount Pictures, Colbert became one of the few major actresses of the period who worked freelance, independent of the studio system.
