Arsinoe was a city on the coast of ancient Cilicia between Anemurium and Kelenderis; the site is near the modern city of Bozyazı, Mersin Province, Turkey. Strabo mentions Arsinoe as having a port. In the 19th century, William Martin Leake placed it at or near the ruined modern castle, called Softa Kalesi, just west of Bozyazı, below which is a port, such as Strabo describes at Arsinoe, and a peninsula on the east side of the harbor covered with ruins. This modern site is east of Anemurium, and west of, and near to, Kızil Burnu.
