The Navajo Nation (Navajo: Naabeehó Bináhásdzo) is a Native American territory covering about 17,544,500 acres (71,000 km2; 27,413 sq mi), occupying portions of northeastern Arizona, southeastern Utah, and northwestern New Mexico in the United States. This is the largest land area retained by a Native American tribe in the United States. In 2010, the total population of Navajo tribal members was 332,129 with 173,667 living within the boundaries of the reservation and 158,462 tribal members outside of the reservation. Metropolitan areas accounted for 26 percent of the population, border towns accounted for ten percent, and the remaining 17 percent were living elsewhere in the U.S.

By area, the Navajo Nation is larger than ten U.S. states – West Virginia, Maryland, Hawaii, Massachusetts, Vermont, New Hampshire, New Jersey, Connecticut, Delaware and Rhode Island – and the territory of Puerto Rico. It is less than one percent shy of being equal to the combined area of the last five states (New Hampshire through Rhode Island).

The United States took over this territory in 1848 after acquiring it in the Mexican-American War. The reservation was within New Mexico Territory and straddled what became the Arizona-New Mexico border in 1912, when the states were admitted to the union. Unlike many reservations, it has expanded several times since its establishment in 1868 to include most of northeastern Arizona, a sizable portion of northwestern New Mexico, and most of the area south of the San Juan River in southeastern Utah. It is one of a few indigenous nations whose reservation lands overlap its traditional homelands.
