The Walloon Legion (French: Légion Wallonie) was a collaborationist military formation recruited among French-speaking volunteers from German-occupied Belgium, notably from Brussels and Wallonia, during World War II. Created in July 1941 shortly after the German invasion of the Soviet Union, the unit was supported by the Rexist Party as a demonstration of its loyalty towards Nazi Germany. It served on the Eastern Front, initially as a unit of the Wehrmacht and, after June 1943, in the Waffen-SS.
