The Susquehannock Trail System (often abbreviated STS, and also known as the Susquehannock Trail) is an 85-mile (137 km) loop hiking trail in the Susquehannock State Forest in Potter and Clinton counties in north-central Pennsylvania in the United States. The trail goes through three state parks and passes within 2 miles (3 km) of three more state parks. Other highlights include a fire tower, vistas, and the Hammersley Wild Area, the largest area in Pennsylvania without a road. The STS was founded by William Fish Jr. in 1966 and is maintained by the Susquehannock Trail Club in cooperation with the Pennsylvania Department of Conservation and Natural Resources (DCNR). In the south it shares 8.7 miles (14.0 km) of its course in Clinton County with the 90-mile (140 km) Donut Hole Trail. The STS also connects to the east with the Black Forest Trail in Lycoming County via two short link trails.

The Susquehannock Trail System is a loop 85 miles (137 km) long, of which 83 miles (134 km) are within the Susquehannock State Forest. The trail has three main access points, all in Potter County. The "Northern Gateway" is at the Susquehannock State Forest headquarters on U.S. Route 6 between the villages of Sweden Valley and Walton in Sweden Township. Another access point for the northern section of the STS is at Lyman Run State Park in West Branch Township; an access trail runs 1.5 miles (2.4 km) west from the southern end of the lake to the main trail. The "Southern Gateway" is at Ole Bull State Park on Pennsylvania Route 144 in Stewardson Township.
