Native American reservations in the United States serve as important cultural and historical landmarks. They represent diverse indigenous communities and offer a chance for them to continue celebrating their heritage.

These reservations are all in the western United States. While large in area, the populations are small.

Below, we’ll discuss in more detail the top 11 largest Native American reservations in the country.

The Navajo Nation Reservation is approximately 27,000 square miles or 16 million acres. It is primarily located in Arizona but reaches into New Mexico and Utah. Navajo Nation has a population of about 173,000 residents, making it the largest Native American reservation in the United States. 

The reservation boasts diverse ecosystems, including deserts, mountains, and canyons. That means it provides ample habitats for a variety of wildlife species. Some of the species living in the region include the coyote (Canis latrans), bobcat (Lynx rufus), pronghorn antelope (Antilocapra americana), and golden eagle (Aquila chrysaetos).

The Navajo Nation’s history dates back centuries. The Navajo people, also known as Diné, have endured hardships, including the Long Walk forced relocation by the U.S. government in the 1860s. They returned to their homeland after a treaty signing in 1868.
