Perga was an ancient and important city of Pamphylia, between the rivers Catarrhactes and Cestrus.

A treaty between the Hittite Great King Tudhaliya IV and his vassal, the king of Tarhuntassa, defined the latter's western border at the city "Parha" and the "Kastaraya River". The river is assumed to be the classical Cestrus. West of Parha were the "Lukka Lands". Parha likely spoke a late Luwian dialect like Lycian and that of the neo-Hittite kingdoms.

Perge returns to history as a Pamphylian Greek city, and with Pamphylia came under successive rule by Persians, Athenians, and Persians again. Alexander the Great, after quitting Phaselis, occupied Perge with a part of his army. The road between these two towns is described as long and difficult. Alexander's rule was followed by the Diadochi empire of the Seleucids, then the Romans.
