Iñupiaq , Inupiaq, Iñupiat , Inupiat, Iñupiatun or Alaskan Inuit is an Inuit language, or perhaps languages, spoken by the Iñupiat people in northern and northwestern American Alaska, as well as a small adjacent part of the Canadian Northwest Territories. The Iñupiat language is a member of the Inuit-Yupik-Unangax language family, and is closely related to (but not mutually intelligible with) other Inuit languages of Canada and Greenland. There are roughly 2,000 speakers. It is considered a threatened language with most speakers at or above the age of 40. Iñupiaq is an official language of the State of Alaska.

The main varieties of the Iñupiaq language are North Slope Iñupiaq and Seward Peninsula Iñupiaq.

The Iñupiaq language has been in decline since contact with English in the late 19th century. American territorial acquisition and the legacy of boarding schools have created a situation today where a small minority of Iñupiat speak the Iñupiaq language. There is, however, revitalization work underway today in several communities.
