Kaunos was a city of ancient Caria and in Anatolia, a few kilometres west of the modern town of Dalyan, Muğla Province, Turkey.

Caria was a region of western Anatolia extending along the coast from mid-Ionia (Mycale) south to Lycia and east to Phrygia. The Carians were described by Herodotus as being Anatolian mainlanders and they called themselves Caria because of the name of their king. He reports the Carians themselves maintained that they were Anatolian mainlanders intensely engaged in seafaring and were akin to the Mysians and the Lydians. The Carians spoke Carian, a native Anatolian language closely related to Luwian. Also closely associated with the Carians were the Leleges, which could be an earlier name for Carians.
