Princeton (originally Vermilion Forks) is a town in the Similkameen region of southern British Columbia, Canada. It lies just east of the Cascade Mountains, which continue south into Washington, Oregon and California. The Tulameen and Similkameen Rivers converge here. At the 2011 census, the population was 2,724.
Princeton centers on seven blocks of businesses along Bridge Street and five blocks on Vermilion Avenue; there are also businesses along British Columbia Highway 3.
Historically, the area's main industry has been mining—copper, gold, coal, and some platinum—but nowadays the town's biggest employer is a sawmill owned by Weyerhaeuser, along with a few smaller timber companies, such as Princeton Wood Preservers and Princeton Post and Rail.
