The Flemish Legion (Dutch: Vlaams Legioen) was a collaborationist military formation recruited among Dutch-speaking volunteers from German-occupied Belgium, notably from Flanders. It fought on the Eastern Front during World War II. The Flemish Legion was notionally an independent formation attached to the Waffen SS until May 1943 when it was disbanded and reformed as the SS-Sturmbrigade Langemarck within the Waffen SS itself.
