Location of the mouth of the Tioga River in New York State.

The Tioga River (/ˈtɡə/ TIE-o-guh) is a tributary of the Chemung River, approximately 58 miles (93 km) long, in northern Pennsylvania and western New York in the United States. It drains a region of ridges in the northern Allegheny Plateau in the watershed of the Susquehanna River.

In the 19th century, trees logged in the Tioga Valley were extensively used in shipbuilding. Logs were floated down the Tioga and the Chemung to the Susquehanna River and on to the Chesapeake Bay and the shipyards of Baltimore.

The Tioga River rises in the mountains of western Bradford County and flows initially southwest into Tioga County, passing through Tioga State Forest. In southern Tioga County it turns north, cutting gaps in four separate ridges while flowing past Blossburg and Mansfield, then through Tioga Reservoir. North of Tioga it receives Crooked Creek from the west, then crosses into Steuben County, New York, near Lawrenceville, Pennsylvania. It receives the Cowanesque River from the west approximately one mile (1.6 km) north of the state line, then receives the Canisteo River from the west in southeastern Steuben County, approximately 10 miles (16 km) southwest of Corning. It joins the Cohocton River at Painted Post, just west of Corning, to form the Chemung River, a tributary of the Susquehanna.
