The Plains Apache language was a Southern Athabaskan language formerly spoken by the Plains Apache, organized as the Apache Tribe of Oklahoma, living primarily around Anadarko in southwest Oklahoma.^[1] The language is extinct as of 2008, when Alfred Chalepah, Jr., the last native speaker, died.^[2]

Plains Apache is the most divergent member of the Southern Athabaskan languages, a family which also includes Navajo, Chiricahua Apache, Mescalero Apache, Lipan Apache, Western Apache, and Jicarilla Apache. As a member of the broader Athabaskan family, it has an extremely complex system of verbal morphology, often enabling entire sentences to be constructed with only a verb.
