Duke of Huéscar (Spanish: Ducado de Huéscar) is a hereditary title in the Spanish nobility. The title was created in 1563 by King Philip II of Spain, and bestowed on Fadrique Álvarez de Toledo y Enríquez, 6th Marquis of Coria, son and heir of Fernando Álvarez de Toledo, 3rd Duke of Alba. It was granted as a title for the male heirs apparent of the subsequent dukes of Alba, who until then held the marquisate of Coria before succeeding to the dukedom. Its name refers to the village of Huéscar, Granada, one of the manors of the house.
