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.

Inuit are a group of culturally and historically similar Indigenous peoples traditionally inhabiting the Arctic and subarctic regions of North America, including Greenland, Labrador, Quebec, Nunavut, the Northwest Territories, Yukon (traditionally), Alaska, and Chukotsky District of Chukotka Autonomous Okrug, Russia. Inuit languages are part of the Eskimo–Aleut languages, also known as Inuit-Yupik-Unangan, and also as Eskaleut. Inuit Sign Language is a critically endangered language isolate used in Nunavut.
