History
The first settlers arrived in 1773-1774, having purchased the land from the descendants of William Penn; other pioneers soon bought land from the state government.
In 1912, Mount Lebanon Township was incorporated as a "First Class Township" under Pennsylvania state law. It had formerly been a part of Scott Township, which in turn traces its origins to the long-defunct St. Clair Township. Mount Lebanon was not named for two Cedar of Lebanon trees that were planted in 1850 on Washington Road near the top of Bower Hill Road, but was named after the area from which they came, Mount Lebanon, due to the similarities between the two landscapes. Prior to the incorporation of the township, the "Mount Lebanon" name was used for the area of Upper St. Clair Township near the cedar trees. In the 1880s, a post office located near the transplanted cedar trees was named "Mount Lebanon". Incorporators of neighboring Dormont Borough initially tried to use the "Mount Lebanon" name in 1909, but were opposed by residents of the future Mount Lebanon Township.
