The indigenous peoples of the Americas are the descendants of the pre-Columbian inhabitants of the Americas. Pueblos indígenas (indigenous peoples) is a common term in Spanish-speaking countries. Aborigen (aboriginal/native) is used in Argentina, whereas "Amerindian" is used in Quebec, The Guianas, and the English-speaking Caribbean. Indigenous peoples are commonly known in Canada as Aboriginal peoples, which include First Nations, Inuit, and Métis peoples. Indigenous peoples of the United States are commonly known as Native Americans or American Indians, and Alaska Natives. 

According to the prevailing theories of the settlement of the Americas, migrations of humans from Asia (in particular North Asia) to the Americas took place via Beringia, a land bridge which connected the two continents across what is now the Bering Strait. The majority of experts agree that the earliest pre-modern human migration via Beringia took place at least 13,500 years ago, with disputed evidence that people had migrated into the Americas much earlier, up to 40,000 years ago. These early Paleo-Indians spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of creation myths.
