Cascade Township is a township in Lycoming County, Pennsylvania. The population was 419 at the 2000 census. It is part of the Williamsport, Pennsylvania Metropolitan Statistical Area.
Cascade Township is bordered by McIntyre Township to the north, McNett Township to the north and east, Plunketts Creek Township to the east, Gamble Township to the south, and Lewis Township to the west.
Cascade Township was formed from parts of Hepburn and Plunketts Creek Townships on 9 August 1843. It is named for the series of waterfalls or cascades that are abundant in the many mountain streams of Cascade Township.
Many of the early settlers in Cascade Township were Irish Catholic. Under the leadership of Michael Kelly they established the village of Kellyburg in one of the most remote parts of Lycoming County. Michael Kelly also cut a road deep into Cascade Township from a sawmill along Lycoming Creek. He built a gristmill and a sawmill in the township. Kelly who had helped establish Cascade Township left the area in 1877 following a bitter defeat in the sheriff election of 1872. He moved to Kansas where he lived until he died in 1883. Michael Kelly also helped his fellow Catholics establish the mission parish of St. Mary's.
