Alraune is a 1918 Hungarian science fiction horror film directed by Michael Curtiz and Edmund Fritz. It starred Géza Erdélyi. Little is known about this film, which is now believed to be lost. Alraune is German for "Mandrake". The film is based on a novel by German novelist Hanns Heinz Ewers published in 1911.

The plot is a variation on the original legend of Alraune, in which a mad scientist creates a beautiful—but demonic—child from the forced union between a woman and a mandrake root fed by the blood of a hanged man.
