Queen of the Night (German: Königin einer Nacht) is a 1931 French musical comedy film directed by Fritz Wendhausen and starring Friedl Haerlin, Karl Ludwig Diehl and Walter Janssen. It is an operetta film. It is the German-language version of the French film La Femme d'une nuit. A separate Italian version was also made. Multiple-language versions were a common feature of the early years of sound before dubbing became firmly established. The film's sets were designed by the art director Pierre Schild.
