The Naryn (, , "Narym") is a river in Eastern Kazakhstan, a tributary of the Irtysh, originating at the junction of the ridges Narym and Sarymsakty of wetland formed by the mountain runoff streams.

The width of the river is , and the depth varies from . Before 1960, the Naryn flowed directly into the Irtysh River, and at the mouth of the river was a village, Ust-Narym. Since 1960, with the construction of  Bukhtarma reservoir that flooded surrounding settlements, the Naryn empties into the Buhtarma Reservoir, and at the mouth of the river lies the village Ulken Naryn. Along the river are the towns Juldyz, Novoberezovka, and Maymyr. According to the Chinese annals, the basin of the Naryn river was a home of an eastern Hun tribe Ala-at, Tr. for "skewbald horse", called in the Chinese annals "He-la" and "Boma" ("skewbald horse"); from the Alat tribe originated one of the Eastern Hun Shanuys called Helog Tou, i.e. Alat Tou, most likely named after his maternal tribe. Modern descendants of the ancient  Alats are Alats in the Altai, and Khalaches and Khalajes in the northern India and eastern section of the Iranian plateau. Under Arabicized name Khalajes, Alats are known to constitute one of the major tribes of the 5th- to 6th-century CE Hephthalites. References. Source - Russian Wikipedia
