Caspians ( Kaspioi, Aramaic: kspy, kaspielebiʿ, kaspkʿ, ) is the English version of a Greek ethnonym mentioned twice by Herodotus among the satrapies of Darius and applied by Strabo to the ancient people dwelling along the southern and southwestern shores of the Caspian Sea, in the region which was called Caspiane after them. The name is not attested in Old Iranian.
