Chiricahua (ˌtʃɪrɪˈkɑːwə ) is a band of Apache Native Americans. Based in the Southern Plains and Southwestern United States, the Chiricahua (Tsokanende ) are related to other Apache groups: Ndendahe (Mogollon, Carrizaleño), Tchihende (Mimbreño), Sehende (Mescalero), Lipan, Salinero, Plains, and Western Apache. Chiricahua historically shared a common area, language, customs, and intertwined family relations with their fellow Apaches. At the time of European contact, they had a territory of 15 million acres (61,000 km2) in Southwestern New Mexico and Southeastern Arizona in the United States and in Northern Sonora and Chihuahua in Mexico. Today Chiricahua live in Northern Mexico and in the United States where they are enrolled in three federally recognized tribes: the Fort Sill Apache Tribe, located near Apache, Oklahoma, with a small reservation outside Deming, New Mexico; the Mescalero Apache Tribe of the Mescalero Reservation near Ruidoso, New Mexico; and the San Carlos Apache Tribe in southeastern Arizona. The Chiricahua Apache, also written as Chiricagui, Apaches de Chiricahui, Chiricahues, Chilicague, Chilecagez, and Chiricagua, were given that name by the Spanish. The White Mountain Coyotero Apache, including the Cibecue and Bylas groups of the Western Apache, referred to the Chiricahua by the name Ha'i’ą́há, while the San Carlos Apache called them Hák'ą́yé which means ′′Eastern Sunrise′′, or ′′People in the East′′. Sometimes they adapted this appellation and referred to themselves also as Ha’ishu Na gukande ('Sunrise People'). The Mescalero Apache called the Western Apache and Chiricahua bands to their west Shá'i'áõde ("Western Apache People", "The People of the Sunset", "The People of the West"), when referring only to Chiricahuas they used Ch'úk'ânéõde ("People of a ridge or mountainside [made of loose rocks]") or sometimes Tã'aa'ji k'ee'déõkaa'õde ("The Ones who are Covered [with breech cloths]"). Navajo refer to the Chiricahua as Chíshí ("Southern People").
