The Cavalry Corps () was a French mechanized army corps established in 1939 and inactivated in 1940 after the defeat of France by Germany. Commanded by General René Prioux, the Cavalry Corps advanced into Belgium in May 1940 and imposed significant delay on the advance of the German XVI (motorized) Corps. Cut off by German forces from the bulk of the French Army, the corps was evacuated to England and then shipped back to France in late May and early June 1940. Further combat resulted in significant losses of armored vehicles and a steady deterioration of the corps' combat power. The Cavalry Corps ceased fighting as the Second Armistice at Compiègne took effect, and the corps was demobilized on July 11, 1940.
