The Navajo also spelled Navaho are a Native American people of the Southwestern United States. Today, the Navajo Nation is the largest federally recognized tribe in the United States. The reservation straddles the Four Corners region in Arizona, Utah, and New Mexico. The Navajo Reservation is slightly larger than the state of West Virginia. The Navajo language is spoken throughout the region, and most Navajos also speak English.

The states with the largest Navajo populations are Arizona and New Mexico. Besides the Navajo Nation proper, a small group of Navajos are members of the federally recognized Colorado River Indian Tribes.

The name “Navajo” comes from the late 18th century via the Spanish (Apaches de) Navajó “(Apaches of) Navajó”, which was derived from the Tewa navahū “farm fields adjoining a valley”. The Navajos call themselves Diné.

Like other Apacheans, the Navajos were semi-nomadic from the 16th through the 20th centuries. Their extended kinship groups had seasonal dwelling areas to accommodate livestock, agriculture, and gathering practices. There is a system of clans which defines relationships between individuals and families.
