La Maldicion de la Bestia (The Curse of the Beast) is a 1975 Spanish horror film that is the eighth in a long series about the werewolf Count Waldemar Daninsky, played by Paul Naschy. The film has also been known as The Werewolf and the Yeti, Night of the Howling Beast and Hall of the Mountain King. This film ignored the events from the earlier Hombre Lobo films and provided an all-new origin for Waldemar's lycanthropy, having the curse transmitted to Waldemar by the bites of two female werewolves. A yeti is woven into the storyline (as in The Fury of the Wolfman), but in this film the Yeti is not the direct cause of Waldemar's lycanthropy. Fernando Florido and Adolfo Ponte handled the special effects throughout the film.

The film premiered at the Sitges International Film Festival in Spain in October 1975, where Naschy was awarded Best Actor for his role in the film. The film was first shown theatrically in Spain in December 1975 as La Maldicion de la Bestia.

An English-dubbed international version was created and titled The Werewolf and the Yeti. But when the film was finally theatrically released in the U.S. in 1977, it was shown instead as Night of the Howling Beast. It was years later released on DVD as The Werewolf and the Yeti

Naschy followed up this film with a 1980 sequel called El Retorno del Hombre Lobo/Return of the Wolf Man.
