The hereditary Spanish title duke of Gandía (, ) has its origin in the "Manorialism of Gandía" founded in 1323 by James II of Aragon and was created in 1399 as Duke of Gandía by Martin of Aragon and granted to Alfonso of Aragon and Foix. Later, having no direct descendants, the title passed from the House of Aragon to the House of Trastámara. The title was re-established in 1483 by Ferdinand II of Aragon as a favour to Cardinal Rodrigo Borgia for his son Pedro Luis (Pier Luigi de Borgia).
