Charles III, Duke of Bourbon (17 February 1490 – 6 May 1527) was a French military leader and noble. He was the count of Montpensier, Clermont-en-Auvergne, and dauphin of Auvergne from 1501 to 1525, and then duke of Bourbon and Auvergne, count of Clermont-en-Beauvaisis, Forez and La Marche, and lord of Beaujeu from 1505 to 1521. He was also the constable of France from 1515 to 1521. Also known as the Constable of Bourbon, he was the last of the great feudal lords to openly oppose the king of France. Bourbon and Francis I of France finally fell out over disputes concerning inheritance. Bourbon commanded the troops of Holy Roman Emperor Charles V in what became known as the Sack of Rome in 1527, where he was killed.
