In 1775, Quemahoning Township was organized, by the Bedford County Court, out of part of Brothersvalley and Turkeyfoot townships. At that time, it included the northern portion of present-day Somerset County and part of what is now Cambria County. Its size was later reduced through the formation of new townships. When Somerset County was established in 1795 Quemahoning was one of the six original townships. The name is a Native American name meaning "pine tree lick," with "cuuni" indicating a pine grove and "mahoni" meaning water from a lick.
