Paphlagonia (/ˌpæfləˈɡoʊniə/; Greek: Παφλαγονία, romanized: Paphlagonía, modern translit. Paflagonía; Turkish: Paflagonya) was an ancient region on the Black Sea coast of north-central Anatolia, situated between Bithynia to the west and Pontus to the east, and separated from Phrygia (later, Galatia) by a prolongation to the east of the Bithynian Olympus. According to Strabo, the region was bounded by the river Parthenius to the west and the Halys River to the east. Paphlagonia was said to be named after Paphlagon, a son of the mythical Phineus.
