Koryaks (or Koriak) are an indigenous people of Kamchatka Krai in the Russian Far East, who inhabit the coastlands of the Bering Sea to the south of the Anadyr basin and the country to the immediate north of the Kamchatka Peninsula, the southernmost limit of their range being Tigilsk. They are akin to the Chukchis, whom they closely resemble in physique and manner of life. Also, they are distantly related to the Kamchadal (Itelmens) on the Kamchatka Peninsula. The Koryaks' neighbors are the Evens to the west of Koryak lands, the Alutor to the south on the isthmus of Kamchatka Peninsula, the Kerek to the east, and the Chukchi to the northeast. The Koryak are typically split into two groups: the coastal people Nemelan (or Nymylan) meaning 'village dwellers' due to their sedentary fishing habits; and the inland Koryaks, reindeer herders called Chaucu (or Chauchuven) meaning 'rich in reindeer' who are more nomadic.
