Posada (Latin: Pheronia, Sardinian: Pasada),[3] also previously known as Feronia or Pausata, is a comune (municipality) in the Province of Nuoro in the Italian region Sardinia.

During the Roman period, the town's importance declined with the foundation of nearby Portus Luguidonis.

The ancient part of the town is in a spectacular position on the top of a hill, where it preserves a particular medieval historical center, with ruins of a castle (Castello della Fava) and a square panoramic tower of the 13th century.

The castle has been the equivalent of a holiday residence for the Giudichessa Eleanor of Arborea, and was object of alternate possession by the Giudicato d'Arborea and the Aragon, during the long fight before the Spanish conquest.

The castle became then the seat of the Baron of Posada, a title and a fief created in 1431 for Don Nicolò Carroz and formally ended in 1856, when it was finally bought by the kingdom of Sardinia (the last one of all Sardinian fiefs).
