Vampire in Venice (Italian: Nosferatu a Venezia), also known as Prince of the Night and Nosferatu in Venice is a 1988 Italian supernatural horror film directed by Augusto Caminito and an uncredited Klaus Kinski, and starring Kinski, Christopher Plummer, Donald Pleasence, and Barbara De Rossi. The story follows Professor Paris Catalano (Plummer), who travels to Venice following the trail of the last known appearance of Nosferatu (Kinski), who was seen at Carnival in 1786. Catalano learns through a séance that the vampire is seeking eternal death, and tries to put an end to its existence once and for all.

After securing Kinski for the lead of Nosferatu, producer August Caminito planned a sequel to Werner Herzog's Nosferatu the Vampyre. Caminito originally secured Maurizio Lucidi as the director but later felt that film would be better with a more well known director and a higher budget, leading Lucidi to be dropped as the director in favor of Pasquale Squitieri. Squiteri made several changes to the script which did not appeal to Caminito, which led to him paying Squiteri and terminating his contract. This led to further budget cuts in the film and hiring Mario Caiano on as the director. After clashing with Kinski on set, Caiano left the film leading Caminito to direct the film himself. During filming, Kinski would not follow rehearsal and demanded changes in the actors appearing in the film and often had lighting changed dramatically on set. According to second unit director Luigi Cozzi, Kinski's behaviour on set became so erratic that the entire crew left the set and did not return until Kinski apologized for his behaviour.

After six weeks of filming, Caminito came to the conclusion that he did not have the entire film completed, but that he also could not continue with the project. This led to entire sections of the re-written screenplay by Caminito not being shot, and Caminito making do with what he had. The film premiered at the Venice Film Festival on 9 September 1988 and it was later released theatrically in Italy.
