Louis I, Count of Étampes

Louis I, Count of Étampes (1336–1400), was a French prince of the blood, the elder son of Charles d'Évreux and Maria de La Cerda. He fought at Poitiers in 1356, where he was captured and later ransomed. He married Jeanne de Brienne in 1358, and in 1360 he was one of four princely hostages handed to Edward III to guarantee the Treaty of Brétigny.

Charles V later gave him the lordship of Lunel and sent him on a mission to Pope Urban V. He had no children and died in Paris on 6 May 1400.
