Vampyr (German: Vampyr - Der Traum des Allan Grey) is a 1932 horror film directed by Danish director Carl Theodor Dreyer. The film was written by Dreyer and Christen Jul based on elements from J. Sheridan Le Fanu's "In a Glass Darkly." Vampyr was funded by Nicolas de Gunzburg who starred in the film under the name of Julian West among a mostly non-professional cast.

Gunzberg plays the role of Allan Grey, a student of the occult who enters a small village outside of Paris which is cursed by supernatural creatures known as Vampyrs who lure townspeople to suicide so they can become servants for the devil.

Vampyr was challenging for Dreyer to make as it was his first sound film and had to be recorded in three languages. To overcome this, very little dialogue was used in the film and much of the story is told with silent film-styled title cards. The film was shot entirely on location and to enhance the atmospheric content, Dreyer opted for a washed out, fuzzy appearing photographic technique. The audio editing was done in Berlin where the character's voices, sound effects, and score were added to the film.

Vampyr had a delayed release in Germany and opened to a generally negative reception from audiences and critics. Dreyer edited the film after its German premiere and it opened to far better review at its French debut. Critical reception to the film has become even more favourable with time, critics praising the film's disorienting visual effects and atmosphere. Indeed, some sources claim it to be a truly great work.
