Duke of Épernon

Duke of Épernon (Fr.: duc d'Épernon) was a noble title in the peerage of France granted to Jean Louis de Nogaret de La Valette by Henry III of France in 1581. It is named after Épernon.

Louis de Pardaillan de Gondrin (1707–1743) sold Épernon to Adrien Maurice de Noailles and the title of "Duke of Épernon" fell into disuse.
