Central Alaskan Yup'ik or just Yup'ik (also called Yupik, Central Yup'ik, or indigenously Yugtun) is one of the languages of the Yupik family, in turn a member of the Eskimo–Aleut language group, spoken in western and southwestern Alaska. Both in ethnic population and in number of speakers, Central Alaskan Yup'ik is the largest of the languages spoken by Alaska Natives. As of 2010 it was also the second largest aboriginal language in the United States in terms of numbers of speakers. Yup'ik should not be confused with the related language Yupik spoken in Siberia.
