The Navajo Nation (Navajo: Naabeehó Bináhásdzo), also known as Navajoland, is a Native American reservation of Navajo people in the United States. It occupies portions of northeastern Arizona, northwestern New Mexico, and southeastern Utah. The seat of government is located in Window Rock, Arizona.
At roughly 17,544,500 acres (71,000 km; 27,413 sq mi), the Navajo Nation is the largest Indian reservation in the United States, exceeding the size of ten U.S. states. It is one of the few reservations whose lands overlap the nation's traditional homelands.
