Koryak is a Chukotko-Kamchatkan language spoken by circa 3,000 people (Koryak) in the easternmost extremity of Siberia, mainly in Koryak Okrug. It is mostly a language spoken by Koryaks. Its close relative, the Chukchi language, is spoken by about twice that number. The language together with Chukchi, Kerek, Alutor and Itelmen forms the Chukotko-Kamchatkan language family. Its name in Koryak is нымылан, Nymylan, but the name imposed by the Russians is the most common.
