Lycoming Township was formed from part of Old Lycoming Township. A petition from the residents of the northern part of what was Lycoming Township was submitted on April 26, 1858. The petition asked that Lycoming Township be divided into northern and southern portions. A vote held in the Newberry section of Williamsport agreed with the petitioners. A judge decreed that the northern portion be called "Lycoming Township" and the southern part be named "Old Lycoming Township" on December 2, 1858. The dividing line begins where Beautys Run flows into Lycoming Creek and follows a line of southwestward to Woodward and Anthony townships.[4]
U.S. Route 15, the Appalachian Thruway, passes through the eastern side of the township, following the Lycoming Creek valley. Access is from Exit 140 (Beautys Run Road) and partial Exit 143 (Pennsylvania Route 973). US-15 leads south 8 miles (13 km) to Williamsport, the county seat, and north 40 miles (64 km) to Mansfield. PA-973 leads east 9 miles (14 km) to Warrensville and west the same distance to Salladasburg. Unincorporated communities within Lycoming Township are in the Lycoming Creek valley. From south to north, these are: Fairlawn, Perryville, and Quiggleville (a short distance up the valley of Hoagland Run).
