The Battle of Möckern (also known as the Battle of Dannigkow) was a series of heavy clashes between allied Prusso-Russian troops under Russian commander Peter Wittgenstein and Napoleonic French forces under Eugène de Beauharnais south of Möckern. It occurred on 5 April 1813. It ended in a French defeat and formed the successful prelude to the "Liberation War" against Napoleon (the German name for the German theatre of the War of the Sixth Coalition).
