Charles de Bourbon, Prince de la Roche-sur-Yon, born 1515, died in 1565 in Beaupré, was a prince of the blood of the House of Bourbon. He was the younger son of Louis de Bourbon, Prince of La Roche-sur-Yon, and Louise de Bourbon, Duchess of Montpensier.

He was captured near Chalons-sur-Marne. Released, he was part of the expedition charged with  defending Metz, besieged by Charles V in 1552, then he joined Henry II besieging Renti in Artois. During the French wars of religion, he served in the royal army and took part in the sieges of Bourges and Rouen (1562).
