The Dahae (; Dáoi, Dáai, Dai, Dasai; Sanskrit: Dasa), Daae, Dahas or Dahaeans were a people in ancient Central Asia, a confederation of three tribes: the Parni, Xanthii and Pissuri. They lived in a region on the south-eastern shores of the Caspian Sea (in modern Turkmenistan). The area has consequently been known as Dahestan, Dahistan and Dihistan. Relatively little is known about their way of life. For example, according to A. D. H. Bivar, the capital of "the ancient Dahae (if indeed they possessed one) is quite unknown."
