Death Mills (or Die Todesmühlen) is a 1945 American-German propaganda film directed by Billy Wilder and produced by the United States Department of War. The film was intended for German audiences to educate them about the atrocities committed by the Nazi regime. For the German version, Die Todesmühlen, Hanuš Burger is credited as the writer and director, while Wilder supervised the editing. Wilder is credited with directing the English-language version; however, he later said that he didn't direct anything as "there was nothing to direct".

The film is a much-abbreviated version of German Concentration Camps Factual Survey, a 1945 British government documentary that was not completed until nearly seven decades later.

The German-language version of the film was shown in the US sector of West Germany in January 1946.
