Caria (; from Greek: Καρία, Karia; ) was a region of western Anatolia extending along the coast from mid-Ionia (Mycale) south to Lycia and east to Phrygia.

Pamphylia (; , Pamphylía ) was a region in the south of Asia Minor in Western Asia, between Lycia and Cilicia, extending from the Mediterranean to Mount Taurus (all in modern-day Antalya province, Turkey). It was bounded on the north by Pisidia and was therefore a country of small extent, having a coast-line of only about 120 km (75 miles) with a breadth of about 50 km (30 miles). Under the Roman administration the term Pamphylia was extended so as to include Pisidia and the whole tract up to the frontiers of Phrygia and Lycaonia, and in this wider sense it is employed by Ptolemy.

Paphlagonia (; , modern translit. Paflagonía; ) 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.
