Penn Township was formed in 1828 when Muncy Township was divided for the fourth time. It is named for Penn Township in Berks County, which in turn is named for William Penn, the founder of Pennsylvania. Tobias and Isaac Kepner had migrated to eastern Lycoming County from Berks County and wanted their new home to have the same name as their old home. Much of the history of Penn Township can be found in the history of the Big Runaway and Muncy Township. Lumbering was the dominant industry in Penn Township during the mid-to-late 19th century. A man-made lake, Beaver Lake, was built to supply water power for a sawmill. The sawmill has long since disappeared but the lake remains.
