The Croix de guerre 1939–1945 is a French military decoration, a version of the Croix de Guerre created on 26 September 1939 to honour people who fought with the Allies against the Axis forces at any time during World War II. After Germany invaded and overran mainland France in May 1940, this Croix de Guerre was replaced by the pro-Axis Vichy French government with another Croix with a black-and-green ribbon, while the original was upheld by Free France. Since the triumph of the Free French side in World War II, this version is the only one officially recognized by the French government.
