Kaunos was a city of ancient Caria and in Anatolia, a few kilometres west of the modern town of Dalyan, Muğla Province, Turkey.
The Calbys river was the border between Caria and Lycia. Initially Kaunos was a separate state; then it became a part of Caria and later still of Lycia.
Kaunos was an important sea port, the history of which is supposed to date back to the 10th century BC. Because of the formation of İztuzu Beach and the silting of the former Bay of Dalyan, Kaunos is now located about 8 km from the coast. The city had two ports, the southern port at the southeast of Küçük Kale and the inner port at its northwest.
