The Indigenous peoples of Arizona are the Native American people of the state of Arizona. These include people that have lived in the region since time immemorial; tribes who entered the region centuries ago, such as the Southern Athabascan peoples; and the Pascua Yaqui who settled Arizona in mass in the early 20th century, though small communities had been in the region for hundreds of years prior. Arizona has the third largest Native American population of any U.S. state.
