Daughter of the Night (German: Der Tanz auf dem Vulkan, lit. 'The Dance on the Volcano') is a German drama film directed by Richard Eichberg. The film is about a French aristocrat (played by Bela Lugosi) who falls in love with a Russian nightclub singer, and his attraction to her involves him in a Russian revolutionary movement.

The ten-reel film was originally released in two parts: as Sybil Joung (transl. Sybil Young) and Der Tod des Großfürsten (transl. The Death of the Grand Duke). It received positive reviews from German publications Film und Brettl and Deutsche Lichtspiel-Zeitung.

A condensed version of the film was released in the United States in 1921 retitled Daughter of the Night. This shortened American print is within the collection of the George Eastman House.
