Requiem is a 2006 German drama film directed by Hans-Christian Schmid. It stars Sandra Hüller as a woman with epilepsy, Michaela Klingler, believed by members of her church and herself to be possessed. The film steers clear of special effects or dramatic music and instead presents documentary-style film making, which focuses on Michaela's struggle to lead a normal life, trapped in a limbo which could either represent demonic possession or mental illness, focusing on the latter.

The film focuses on the medical condition of epilepsy as seen in the real-life events of Anneliese Michel, a German woman who was allegedly possessed by six or more demons and died in 1976. These events also served as the basis of Scott Derrickson's 2005 film The Exorcism of Emily Rose.
