The Western Apache live primarily in east central Arizona, in the United States and north of Mexico in the states of Sonora and Chihuahua. Most live within reservations. The Fort Apache Indian Reservation, San Carlos Apache Indian Reservation, Yavapai-Apache Nation, Tonto Apache, and the Fort McDowell Yavapai Nation are home to the majority of Western Apache and are the bases of their federally recognized tribes. In addition, there are numerous bands. The Western Apache bands call themselves Ndee (Indé). Because of dialectical differences, the Pinaleño/Pinal and Arivaipa/Aravaipa bands of the San Carlos Apache pronounce the word as Innee or Nnēē:.

The Yavapai are a Native American tribe in Arizona. Historically, the Yavapai – literally “people of the sun” – were divided into four geographical bands who identified as separate, independent peoples: the Ɖulv G’paaya, or Western Yavapai; the Yaavpe', or Northwestern Yavapai; the Gwev G’paaya, or Southeastern Yavapai; and the Wiipukpaa, or Northeastern Yavapai – Verde Valley Yavapai.
