Five Major Cultural Regions of Native American Tribes in North America

Anthropologists and historians commonly group the diverse Indigenous nations of North America into distinct cultural areas based on shared environmental adaptations, social structures, and traditions. According to the Native Tribes Guide, five primary regions encompass the majority of tribal nations:

1. Northeastern Woodlands – Tribes of the forests and river valleys from the Atlantic coast to the Great Lakes.
2. Southeastern Woodlands – Nations of the humid, fertile Southeast, known for mound-building and agriculture.
3. Western Plateau – Peoples of Idaho, Oregon, western Montana, Utah, and Nevada, adapted to basin and range geography.
4. Great Plains and Prairie – Stretching from Canada to Central Texas, home to nomadic bison-hunting cultures.
5. Southwest – Encompassing Arizona and New Mexico, featuring Puebloan and desert-adapted societies.

Note that Southern California is sometimes treated as a distinct sixth area due to its unique coastal and desert adaptations. These cultural areas reflect broad patterns; each contains numerous distinct tribes with their own languages, customs, and histories.
