The XII Corps of the Grande Armée was the name of a short-lived French military unit that existed during the Napoleonic Wars. The corps was formed in the spring of 1813 and Marshal Nicolas Oudinot was appointed as its commander. The formation included one Bavarian and two French infantry divisions. In the spring campaign the corps was engaged at Lützen, Bautzen, and Luckau. After the summer 1813 armistice, the corps fought at Grossbeeren and Dennewitz. After the latter action, Emperor Napoleon dissolved the corps and assigned its units to other formations. Oudinot found employment as a commander of two divisions of the Young Guard.
