The German Corpse Factory or Kadaververwertungsanstalt, also sometimes called the "German Corpse-Rendering Works" or "Tallow Factory" was one of the most notorious anti-German atrocity propaganda stories circulated in World War I. In the postwar years, investigations in Britain and France revealed that these stories were false.

Atrocity propaganda is the spreading of information about the crimes committed by an enemy, which can be factual, but often includes or features deliberate fabrications or exaggerations. This can involve photographs, videos, illustrations, interviews, and other forms of information presentation or reporting.
