Kameiros (/kəˈmaɪərəs/; Greek:Κάμειρος) is an ancient city on the island of Rhodes, in the Dodecanese, Greece. It lies on the northwest coast of the island, three km west of the village of Kalavarda.

The ancient city was built on three levels. At the top of the hill was the acropolis, with the temple complex of Athena Kameiras and the stoa. A covered reservoir having a capacity of 600 cubic meters of water—enough for up to 400 families—was constructed about the sixth century BC. Later, the stoa was built over the reservoir. The stoa consisted of two rows of Doric columns with rooms for shops or lodgings in the rear.
