Charles III (1620 – 4 May 1692) was the third Duke of Elbeuf and member of the House of Lorraine.

He was also a Peer of France as well as titular Duke of Guise, Count of Harcourt, Lillebonne and Rieux.

Charles was born at the Hôtel d'Elboeuf in Paris and was the eldest son of Charles II, Duke of Elbeuf, and his wife Catherine Henriette de Bourbon,[1] legitimised daughter of Henry IV of France and Gabrielle d'Estrées.

Charles took great part in the Thirty Years' War; he was with le Grand Condé (then the Duke of Enghien) at the famous victory at Rocroi in 1643.

Some time after in 1661, Louis XIV started his personal reign and named Charles as the Governor General of Picardy and Artois, a post his father had previously occupied.
