The IV Cavalry Corps of the Grande Armée was a French military unit that existed during the Napoleonic Wars. The corps was created in 1812 and rebuilt in 1813 and 1815. Emperor Napoleon I first organized the corps for the invasion of Russia. Under General Victor de Fay de La Tour-Maubourg, the corps fought at Borodino. During the War of the Sixth Coalition in 1813, General François Étienne de Kellermann commanded the all-Polish corps at Leipzig.
