The Itelmen, sometimes known as Kamchadal, are an ethnic group who are the original inhabitants living on the Kamchatka Peninsula in Russia. The Itelmen language (ethnonym: Itelmen) 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.
