Gulf of Gökova

Gulf of Gökova (Turkish: Gökova Körfezi) or Gulf of Kerme (Turkish: Kerme Körfezi, Greek: Κεραμεικός κόλπος, Latin: Ceramicus Sinus, English: Ceramic Gulf or Gulf of Cos), is a long (100 km), narrow gulf of the Aegean Sea between Bodrum Peninsula and Datça Peninsula in south-west Turkey.

Administratively, Gulf of Gökova coastline includes portions of the districts of, clockwise, Bodrum, Milas, Muğla, Ula, Marmaris and Datça. The Greek island of Kos lies along the entry into the Gulf.

Bodrum, located in its northwest reaches, is the only large city on the gulf today. In ancient times, alongside Halicarnassus (modern-day Bodrum), the city of Ceramus, located midway along the gulf's northern shore and after which the gulf was named, was also an important urban center. Across Ceramus (Gereme) (in the modern township of Ören, at a short distance from the gulf's southern shore and not far from its outlying waters, was another historical site of note, called Cedrae in ancient times. Cedrae was located in Sedir Island, which was prized by visitors for its beach and of which some remains still exist.
