Historical distribution of Southern Athabaskan languages

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 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.

Self-designations for Western Apache and Navajo are N'dee biyat'i, and Diné bizaad or Naabeehó bizaad, respectively.

There are several well-known historical people whose first language was Southern Athabaskan. Geronimo (Goyaałé) who spoke Chiricahua was a famous raider and war leader. Manuelito spoke Navajo and is famous for his leadership during and after the Long Walk of the Navajo.
