Patrimonio Nacional (English: National Heritage) is a Spanish autonomous agency, under the jurisdiction of the Ministry of the Presidency, Justice and Relations with the Cortes, that administers the sites owned by the Spanish State and used by the Monarch and the royal family as residences and for State ceremonies. The Patrimonio Nacional includes palaces, gardens, monasteries and convents, called the Royal sites. When not in official use, the Royal sites are open to the public. It also manages the official and holiday residences of the Prime Minister.

The agency was first created in 1865 during the reign of Isabella II under the name of Patrimonio de la Corona (English: Heritage of the Crown). During the reign of her grandson, Alfonso XIII, it was also known as Patrimonio Real (English: Royal Heritage). The second republic (1931–1939) kept the agency under the name of Patrimonio de la República ,(English: Heritage of the Republic), and it has been called by its current name since in 1940, when it was renamed Patrimonio National by the dictator Francisco Franco.
