Cataonia (Ancient Greek: Kαταoνία) was one of the divisions of ancient Cappadocia.
It is described by Strabo, who had visited it, as a level plain surrounded by mountain- on the south by the Amanus, and on the west by the Antitaurus, which branches off from the Cilician Taurus and contains deep narrow valleys (in one of which was situated Comana, a considerable city on the river Sarus, which flows through the gaps of the Taurus into Cilicia and the Mediterranean). Through the plain of Cataonia flows the river Pyramus, which has its source in the middle of the plain, and also passes through the gaps of the Taurus into Cilicia. The plain is very productive, except that it has no evergreens. Strabo speaks of a temple of Zeus Dacius, where there is a salt-lake of the considerable extent with steep banks, so that the descent to it is like going down steps; it was said that the water never increased, and had no visible outlet.
