The Icarian Sea (Greek: Ικάριο Πέλαγος, Ikario Pelagos) is a subdivision of the Mediterranean Sea that lies between the Cyclades and Asia Minor. It is described as the part of the Aegean Sea to the south of Chios, to the east of the Eastern Cyclades and west of Anatolia. It contains the islands of Samos, Cos, Patmos, Leros, Fournoi Korseon and Icaria.
It is the place, in myth, into which Icarus made his fatal fall from the sky during his flight from Crete with his father Daedalus. It is either directly from this legend that it gets its name, or from the island of Icaria.
