The XI Corps of the Grande Armée was the name of a French military unit that existed during the Napoleonic Wars. In 1809 during the War of the Fifth Coalition, General of Division Auguste Marmont's Army of Dalmatia was renamed the XI Corps. Emperor Napoleon I held it in reserve at the Battle of Wagram. In 1812, the unit was reconstituted during the invasion of Russia and placed under Marshal Pierre Augereau. It did not fight in any battles and instead served a collection point for reserves. In spring 1813, it was reorganized and placed under the command of Marshal Jacques MacDonald. The corps fought at Lutzen, Bautzen, the Katzbach, Leipzig, and Hanau in 1813. Still under MacDonald, the unit fought at Bar-sur-Aube and several minor actions in 1814.
