Chevak Cup’ik or just Cup’ik (and sometimes Cugtun) is a subdialect of Hooper Bay–Chevak dialect of Yup'ik spoken in southwestern Alaska in the Chevak (Cup'ik, Cev’aq) by Chevak Cup’ik Eskimos (own name Cup’it or Cev’allrarmuit). The speakers of the Chevak subdialect used for themselves as Cup'ik (as opposed to Yup'ik), but the speakers of the Hooper Bay subdialect used for themselves as Yup'ik (not Cup'ik), as in the Yukon-Kuskokwim dialect.
