The Bridge River Indian Band also known as the Nxwísten First Nation, the Xwisten First Nation, and the Bridge River Band, is a First Nations government located in the Central Interior-Fraser Canyon region of the Canadian province of British Columbia. It is a member of the Lillooet Tribal Council (also known as the St'at'imc Nation), which is the largest grouping of band governments of the St'at'imc people (aka the Lillooet people).
The Bridge River Indian Band's offices are located on BC Highway 40 in the lower Bridge River valley, a few miles outside of Lillooet, British Columbia, which is about 150 miles northeast of Vancouver, British Columbia, on the northern end of the town of Lillooet. Its residential areas are scattered through its reserve, one of the largest in British Columbia, with a newer residential subdivision adjacent to Highway 40 near the band offices, about 15 kilometres from Lillooet. It is one of the three main band communities of "metropolitan Lillooet", the others being the Cayoose Creek Indian Band (Sekwelwas First Nation) and the T'it'kt First Nation Lillooet Band), all of which border on the District of Lillooet.
The important and age-old Bridge River Fishing Grounds, known as Sxetl in the St'at'imcets language and also known locally as Six Mile Rapids, are on the reserves of the Bridge River Band and their original "modern" post-Contact rancherie is on the bench above the fishing grounds, which are also known as the Lower Fountain or Lower Fountains and which lie at the junction of the Bridge and Fraser Rivers.
