Mother Joan of the Angels is a 1961 Polish horror art film on demonic possession, directed by Jerzy Kawalerowicz, based on a novella of the same title by Jarosław Iwaszkiewicz, loosely based on the 17th century Loudun possessions. The film won the Special Jury Prize at the 1961 Cannes Film Festival.

Urbain Grandier was a French Catholic priest who was burned at the stake after being convicted of witchcraft, following the events of the so-called "Loudun possessions". Most modern commentators have concluded that Grandier was the victim of a politically motivated persecution led by the powerful Cardinal Richelieu.
