Karl Friedrich von dem Knesebeck (5 May 1768– 12 January 1848) was a Prussian field marshal and military adviser in the Napoleonic Wars, best known for designing the campaign plan of the Battle of the Nations and the subsequent invasion of France. As aide-de-camp to the king from 1813, and thereby his closest military advisor, he was a key figure in Prussia's military policy throughout the War of the Sixth Coalition and the subsequent Congress of Vienna.
