The II Corps of the Grande Armée was a French military unit that existed during the Napoleonic Wars.

At its formation in 1805, General Auguste de Marmont was appointed commander of the II Corps.

Still under Marmont, the troops then served as the garrison of the Illyrian Provinces until 1809 when they became the Army of Dalmatia and later XI Corps.

Still commanded by Oudinot, the corps took part in the invasion of Russia in 1812, at which point its size was roughly 40,000 men.

The corps was headed by General Honoré Charles Reille in 1815 and took part in the Battle of Waterloo.
