Saria Island (Greek: Σαρία), anciently known as Sarus or Saros (Ancient Greek: Σάρος), is an island in Greece. It is a rocky, volcanic island just to the north of Karpathos, separated from it by a 100 m (330 ft) wide strait. It is part of the Dodecanese archipelago. In ancient times, a city-state called Saros was situated on the island. It was a member of the Delian League.
Administratively, it is part of the municipal unit of Olympos. The 2011 census reported a population of 45 residents. It has little plant or animal life, and has a number of steep cliffs. Although only shepherds live on Saria now, the ruins of the ancient city of Nisyros can be found here. It is also a breeding area for Eleonora's falcons.
