Fraser Valley is the section of the Fraser River basin in southwestern British Columbia downstream of the Fraser Canyon. The term is sometimes used to refer to the Fraser Canyon and stretches upstream from there, but in general British Columbian usage the term refers to the stretch of the river downstream from the town of Hope.
The south shore of the Central and Upper Fraser Valley is also known colloquially as the "Bible Belt" of British Columbia and is home to many of Canada's largest churches, notably the Mennonite Brethren and the Dutch Reformed Church, a reflection of the heavy settlement of the Valley by post-war Dutch and German immigrants, as well as the Canadian headquarters of many Christian/Evangelical para-church organizations such as Focus on the Family and Campus Crusade for Christ. Voters in south shore ridings typically elect conservative candidates, while in riding on the river's north side elections sway between social democratic and conservative parties regularly because of a more diverse range of churches and a much less religious tone and a stronger labour presence there. Abbotsford is also home to the Guru Sikh Temple, Canada's oldest Sikh temple, and Sikh temples are commonplace features of the Fraser Valley landscape.
