The House of the Devil (French: Le Manoir du diable, lit. 'The Devil's Manor'), released in the United States as The Haunted Castle and in the United Kingdom as The Devil's Castle, is an 1896 French silent trick film directed by Georges Méliès. The film, which depicts a brief pantomimed sketch in the style of a theatrical comic fantasy, tells the story of an encounter with the Devil and various attendant phantoms. It is intended to evoke amusement and wonder from its audiences, rather than fear. However, because of its themes and characters, the film has been considered to technically be the first horror film. Such a classification can also be attributed to the film's depiction of a human transforming into a bat, a plot element which has led some observers to label the work the first vampire film. The film is also innovative in length; its running time of over three minutes was ambitious for its era.

A single remake, also by Méliès, was produced one year later under the title Le Château hanté (The Haunted Castle), which is often confused with this film.

The film was presumed lost until 1988, when a copy was found in the New Zealand Film Archive.
