Chukchi (/ˈtʃʊktʃiː/ CHUUK-chee), also known as Chukot, is a Chukotko–Kamchatkan language spoken by the Chukchi people in the easternmost extremity of Siberia, mainly in Chukotka Autonomous Okrug. The language is closely related to Koryak. Chukchi, Koryak, Kerek, Alutor, and Itelmen form the Chukotko-Kamchatkan language family. There are many cultural similarities between the Chukchis and Koryaks, including economies based on reindeer herding. Both peoples refer to themselves by the endonym Luorawetlat (ԓыгъоравэтԓьат [ɬəɣˀorawetɬˀat]; singular Luorawetlan ԓыгъоравэтԓьан [ɬəɣˀorawetɬˀan]), meaning "the real people". All of these peoples and other unrelated minorities in and around Kamchatka are known collectively as Kamchadals.
Chukchi and Chukchee are anglicized versions of the Russian exonym Chukcha (plural Chukchi). This came into Russian from Čävča, the term used by the Chukchis' Tungusic-speaking neighbors, itself a rendering of the Chukchi word чавчыв [tʃawtʃəw], which in Chukchi means "[a man who is] rich in reindeer," referring to any successful reindeer herder, a wealthy man by local standards.
