Koryak (/ˈkɔːriæk/) is a Chukotko-Kamchatkan language spoken by about 1,700 people in the easternmost extremity of Siberia, mainly in Koryak Okrug. It is mostly spoken by Koryaks. Its close relative, the Chukchi language, is spoken by about three times that number. The language together with Chukchi, Kerek, Alutor and Itelmen forms the Chukotko-Kamchatkan language family. Its native name in Koryak is нымылан nymylan, but the Russian name is more common.
