The Allegheny River spans over 325 miles and originates in Potter County, Pennsylvania. It flows through the Allegheny Mountains and ultimately joins the Monongahela River to form the Ohio River. Native American tribes such as the Seneca, Shawnee, and Mohawk once inhabited the region before European settlers arrived in the 1700s. The river's hydrology and course have been altered by various dams, including the Kinzua Dam, which created the Allegheny Reservoir. The Conemaugh River Lake and Tionesta Lake are other major reservoirs along the river. The Allegheny River is used for a variety of recreational activities, such as fishing, boating, and camping. The river is also a source of drinking water for multiple towns and cities, and its watersheds support agricultural industries throughout the region.

The Allegheny River ( AL-ə-GAY-nee) is a 325-mile (523 km) long headwater stream of the Ohio River in western Pennsylvania and New York, United States. The Allegheny River runs from its headwaters just below the middle of Pennsylvania's northern border northwesterly into New York then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio on the "Point" of Point State Park in Downtown Pittsburgh, Pennsylvania. The Allegheny River is, by volume, the main headstream of both the Ohio and Mississippi Rivers. Historically, the Allegheny was considered to be the upper Ohio River by both Native Americans and European settlers.
The shallow river has been made navigable upstream from Pittsburgh to East Brady by a series of locks and dams constructed in the early 20th century. A 24-mile long portion of the upper river in Warren and McKean counties of Pennsylvania and Cattaraugus County in New York is the Allegheny Reservoir also known as Lake Kinzua, created by the erection of the Kinzua Dam in 1965 for flood control.
The name of the river comes from one of a number of Delaware Indian phrases which are homophones of the English name, with varying translations.
