Mescalero-Chiricahua (also known as Mescalero-Chiricahua Apache) is a Southern Athabaskan language spoken by the Mescalero and Chiricahua tribes in Oklahoma and New Mexico. It is related to Navajo and Western Apache. Mescalero-Chiricahua has been described in great detail by the anthropological linguist Harry Hoijer (1904–1976), especially in Hoijer & Opler (1938) and Hoijer (1946). Hoijer & Opler's Chiricahua and Mescalero Apache Texts, including a grammatical sketch and traditional religious and secular stories, has been converted into an online "book" available from the University of Virginia.
