Navajo is the most widely spoken language of the Na-Dené family, spoken in Arizona, New Mexico, and other regions of the American Southwest. Dene or Dine is a widely distributed group of Native languages and peoples spoken in Canada, Alaska, and parts of Oregon and northern California. Eyak is spoken in the Alaskan panhandle and today there is only one speaker left.

According to Joseph Greenberg's highly controversial classification of the languages of Native North America, Na-Dené-Athabaskan is one of the three main groups of Native languages spoken in the Americas, and represents a distinct wave of migration from Asia to the Americas. The other two are Eskimo-Aleut, spoken in Alaska and the Canadian Arctic; and Amerind, Greenberg's most controversial classification, which includes every language native to the Americas that is not Eskimo-Aleut or Na-Dené.

According to the linguistic theory of Sergei Starostin, Na-Dene is a member of the Dene-Caucasian superfamily, along with the North Caucasian languages and Sino-Tibetan languages.
