Pennsylvania Route 115 (PA 115) is a 35.7-mile-long (57.5 km) north–south state highway in eastern Pennsylvania. It stretches from U.S. Route 209 (US 209) in Brodheadsville, Monroe County to Interstate 81 (I-81) and PA 309 near Wilkes-Barre in Luzerne County. PA 115 passes through rural areas along its route, intersecting PA 903 in Tunkhannock Township, I-80 and PA 940 in Tobyhanna Township, and I-476 (Pennsylvania Turnpike Northeast Extension) in Bear Creek Township. The road serves as a connector between The Poconos and the Wyoming Valley.

The road originated as the Sullivan Trail, a route that follows the path taken by General John Sullivan during his expedition in the American Revolutionary War. The Sullivan Trail later became known as the Easton and Wilkes-Barre Turnpike, a turnpike that connected Easton and Wilkes-Barre between 1815 and the 1850s. PA 115 was designated in 1928 to run from Montoursville east to Swiftwater; the route was designated PA 15 for a year prior to that. In 1935, the east end was realigned from Swiftwater to Saylorsburg. By 1937, the termini were moved from Montoursville to Mausdale and from Saylorsburg to Easton. PA 115 was extended west to Milton by 1950. The northern terminus was realigned to Hughesville by 1960, the same time a portion of the route from Saylorsburg to Wind Gap was relocated to a freeway alignment. PA 115's northern terminus was cut back to the Wilkes-Barre area in 1961. The southern terminus was rolled back to Brodheadsville by 1972. PA 115 has had its northern terminus in various locations in the Wilkes-Barre area from 1962 to 1990; finally being moved to its current location in 1990.
