Iñupiaq or Inupiaq, also known as Iñupiat, Inupiat, Iñupiatun or Alaskan Inuit, is an Inuit language, or perhaps group of languages, spoken by the Iñupiat people in northern and northwestern Alaska, as well as a small adjacent part of the Northwest Territories of Canada. The Iñupiat language is a member of the Inuit-Yupik-Unangan language family, and is closely related and, to varying degrees, mutually intelligible with other Inuit languages of Canada and Greenland. There are roughly 2,000 speakers. Iñupiaq is considered to be a threatened language, with most speakers at or above the age of 40. Iñupiaq is an official language of the State of Alaska, along with several other indigenous languages.

The Inuit languages are a closely related group of indigenous American languages traditionally spoken across the North American Arctic and the adjacent subarctic regions as far south as Labrador. The Inuit languages are one of the two branches of the Eskimoan language family, the other being the Yupik languages, which are spoken in Alaska and the Russian Far East. Most Inuit people live in one of three countries: Greenland, a self-governing territory within the Kingdom of Denmark; Canada, specifically in Nunavut, the Inuvialuit Settlement Region of the Northwest Territories, the Nunavik region of Quebec, and the Nunatsiavut and NunatuKavut regions of Labrador; and the United States, specifically in northern and western Alaska.
