Alaska Natives are the Indigenous peoples of Alaska and include Alaskan Creoles, Iñupiat, Yupik, Aleut, Eyak, Tlingit, Haida, Tsimshian, and a number of Northern Athabaskan cultures. They are often defined by their language groups. Many Alaska Natives are enrolled in federally recognized Alaska Native tribal entities, who in turn belong to 13 Alaska Native Regional Corporations, who administer land and financial claims.
