Glaros (Γλάρος, "seagull") or Glaronisi (Γλαρονήσι) is an island that belongs to the Lesser Cyclades. It lies approximately 0.6 nautical miles (1.1 km) south of Koufonisi and is only about five hundred metres east of Kato Koufonisi. Glaros is extremely small, flat, uninhabited and nearly barren. This island can be visited from Koufonisi only with a special arrangement with any of the local boatsmen. There are around five small rocky islets off the east coast of Glaros.
