Cass is a census-designated place (CDP) and unincorporated community on the Greenbrier River in Pocahontas County, West Virginia, United States.

[3] The community, founded in 1901, was named for Joseph Kerr Cass, vice president and cofounder of the West Virginia Pulp and Paper Company.

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 1963, the state bought the logging railroad and converted it into a tourist attraction, carrying passengers into the vast Monongahela National Forest.

Cass Scenic Railroad State Park runs from the town to the half way point called Whittaker Station.
