Romasanta, also known as Romasanta, la caza de la bestia in Spanish, and Romasanta: The Werewolf Hunt in English, is a 2004 Spanish-Italian-British horror film directed by Paco Plaza and starring Julian Sands, Elsa Pataky and John Sharian. It is available on DVD from Lion's Gate Entertainment under the title Werewolf Hunt.

Based on a script by Alfredo Conde, according to the end credits the film is based on a true story, that of Manuel Blanco Romasanta, Spain’s first documented serial killer. Conde is a descendant of one of the doctors involved the original Werewolf of Allariz court case that took place in 1853/54 in Galicia, Spain. He went on to write a fictional novel, The Uncertain Memoirs of a Galician Wolfman: Romasanta. The same case previously provided the basis for the 1968 Spanish film El bosque del lobo ("The Wolf's Forest").
