Southern Athabaskan (also Apachean) is a subfamily of Athabaskan languages spoken primarily in the Southwestern United States (including Arizona, New Mexico, Colorado, and Utah) with two outliers in Oklahoma and Texas. The language is spoken to a much lesser degree in the northern Mexican states of Sonora, Chihuahua, Durango, Coahuila, and Nuevo León. Those languages are spoken by various groups of Apache and Navajo peoples. Elsewhere, Athabaskan is spoken by many indigenous groups of peoples in Alaska, Canada, Oregon and northern California.
