Which neighboring Indigenous peoples lived north of the American Subarctic region?

The Indigenous peoples living north of the American Subarctic region are the Inuit (including the Canadian Inuit) and the Yupik/Yupiit peoples.1

While the American Subarctic is primarily home to Athabaskan and Algonquian speaking groups, these populations border the Inuit to the north. These northern groups are culturally and linguistically distinct from the Subarctic peoples, as they are traditionally tied to the coastal and tundra environments of the Arctic rather than the boreal forest ecosystem that defines the Subarctic region.12
