The Itelmens (Itelmen: Итәнмән, Russian: Ительмены) are an ethnic group native to the Kamchatka Peninsula in Russia. The Itelmen language is distantly related to Chukchi and Koryak, forming the Chukotko-Kamchatkan language family, but it is now virtually extinct, the vast majority of ethnic Itelmens being native speakers of Russian. A. P. Volodin has published a grammar of the Itelmen language.
