Native Americans, also known as American Indians, First Americans, Indigenous Americans and other terms, are the indigenous peoples of the United States, sometimes including Hawaii and territories of the United States and sometimes limited to the mainland. There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations. “Native Americans” (as defined by the United States Census) are Indigenous tribes that are originally from the continental United States, plus Alaska Natives.
Indigenous peoples of the United States who are not American Indian or Alaska Native include Native Hawaiians, Samoans, or Chamorros. The US Census groups these peoples as “Native Hawaiian and other Pacific Islander.”
