Southern Athabaskan is a subfamily of Athabaskan languages spoken primarily in the Southwestern United States with two outliers in Oklahoma and Texas. The languages are spoken in the northern Mexican states of Sonora, Chihuahua, Coahuila and to a much lesser degree in Durango 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.
