Samos (/ˈseɪmɒs/, also US: /ˈsæmoʊs, ˈsɑːmɔːs/; Greek: Σάμος [ˈsamos]) is a Greek island in the eastern Aegean Sea, south of Chios, north of Patmos and the Dodecanese, and off the coast of western Turkey, from which it is separated by the 1.6-kilometre (1.0 mi)-wide Mycale Strait. It is also a separate regional unit of the North Aegean region, and the only municipality of the regional unit. The island was governed by the semi-autonomous Principality of Samos under Ottoman suzerainty from 1835 until it joined Greece in 1912.
