The Blood on Satan's Claw is a 1971 British supernatural period folk horror film directed by Piers Haggard and starring Patrick Wymark, Linda Hayden, and Barry Andrews. Set in early 18th-century England, it follows the residents of a rural village whose youth fall under the influence of a demonic presence after a local farmer unearths a mysterious deformed skull buried in a field. It is widely regarded as one of three films that introduced the folk horror aesthetic to British cinema, an "unholy trinity" whose other entries are Witchfinder General (1968) and The Wicker Man (1973).
