The High Bar First Nation is a First Nations government of the Secwepemc (Shuswap) Nation, located in the Fraser Canyon-Cariboo region of the Central Interior of the Canadian province of British Columbia. It was created when the government of the then-Colony of British Columbia established an Indian Reserve system in the 1860s. It is one of three Secwepemc bands that is not a member of either the Shuswap Nation Tribal Council or the Northern Shuswap Tribal Council.

There are three Indian Reserves under the administration of the High Bar First Nation:
