The Devil Strikes at Night (German: Nachts, wenn der Teufel kam) is a 1957 West German crime thriller film directed by Robert Siodmak and starring Claus Holm, Mario Adorf and Hannes Messemer.

The film's sets were designed by the art directors Gottfried Will and Rolf Zehetbauer.

The film is a highly fictionalized account of the hunt for a serial killer, as he murders women during the last year or two of World War II.

An investigator begins to unravel a thread leading to the real killer, but becomes frustrated by Nazi authorities who believe that revealing the truth will undermine people's faith in their supposedly infallible system.

The detective story gradually evolves into a narrative about the evils of political propaganda and corruption.
