To the Devil a Daughter is a 1976 horror film, directed by Peter Sykes and produced by Hammer Film Productions and Terra-Filmkunst. It is based on the novel of the same name by Dennis Wheatley, and stars Richard Widmark, Christopher Lee, Honor Blackman, Nastassja Kinski and Denholm Elliott. It was the final Hammer production to feature Christopher Lee until The Resident in 2011.

American expatriate occult writer John Verney (Widmark) is asked by Henry Beddows (Elliot) to pick up his daughter Catherine (Kinski) from London airport. Catherine is a nun with the Children of the Lord, a mysterious heretical order based in Bavaria and founded by the excommunicated Roman Catholic priest Michael Rayner (Lee), where Beddows is allowed to come to visit Catherine only on her birthdays. But after Catherine arrives, Beddows then insists that she stay with Verney. The order, however, under Father Michael, makes all efforts to get Catherine back and uses black magic to stop Verney as he protects her. Verney learns that the order really harbours a group of practicing Satanists, who have prepared Catherine to become an avatar of Astaroth upon her eighteenth birthday. The priest kills Verney's friends, and tries to get Verney. Verney battles the priest and his henchmen and is able to rescue Catherine.

The film was adapted by Christopher Wicking and John Peacock from the 1953 novel of the same name by Dennis Wheatley. It was the second of Wheatley's "black magic" novels to be filmed by Hammer, following The Devil Rides Out, released in 1968. Wheatley disliked the film because it did not follow his novel and he found it obscene. He told Hammer that they were not to make another film from his novels ever again.
