Cass is an unincorporated census-designated place on the Greenbrier River in Pocahontas County, West Virginia, USA. As of the 2010 census, its population was 52. The town, founded in 1901, was named for Joseph Kerr Cass, vice president and cofounder of the West Virginia Pulp and Paper Company.
Cass began as a company town for those who worked for West Virginia Pulp and Paper Company, logging the nearby Cheat Mountain. The cut logs were brought by rail to the town, where a processed them for uses by paper and hardwood-flooring companies. Cass's skilled laborers, who worked in the mill or the locomotive-repair shop, lived with their families in 52 white-fenced houses, built in orderly rows on a hill south of the general store.
In 1960 the mill closed. In 1963, the state bought the railroad used to bring logs to the town, which then began carrying tourists instead of trees. In the late 1970s, the state bought most of the town and its buildings for the new Cass Scenic Railroad State Park. In 1982 the mill burned down.
