The Allegheny River rises in north central Pennsylvania, on Cobb Hill in [[Allegany Township, Pennsylvania|Allegany Township]] in north central [[Potter County, Pennsylvania|Potter County]],<ref name=gnis>{{Cite GNIS|1209386|Allegheny River}}</ref><ref name=Sweden>''Sweden Valley, PA,'' 7.5 Minute Topographic Quadrangle, USGS, 1969 (1972 rev.)</ref> {{convert|8|mi|km}} south of the [[New York–Pennsylvania border]] and a few miles northwest of the eastern [[triple divide]]. The stream flows south and passes under [[Pennsylvania Route 49]] 11 miles northeast of [[Coudersport, Pennsylvania|Coudersport]] where a historical marker that declares the start of the river is located. Cobb Hill is about a mile north. The stream flows southwest paralleling Route 49 to Coudersport.<ref name=Sweden/>

The route continues west to [[Port Allegany, Pennsylvania|Port Allegany]], where thereafter the river joins with a number of small streams and widens considerably before turning north and crossing into western New York.<ref>''Bradford, PA,'' 1:100,000 Scale Topographic Map, USGS, 1980</ref> Looping westward across southern [[Cattaraugus County, New York|Cattaraugus County]] for approximately {{convert|30|mi|km}}, past [[Portville, New York|Portville]], [[Olean, New York|Olean]], [[Allegany, New York|Allegany]] and [[Salamanca (city), New York|Salamanca]], the river flows through [[Seneca Nation of New York|Seneca Indian Nation]] lands close to the northern boundary of [[Allegany State Park]] before re-entering [[Northwest Region (Pennsylvania)|northwestern Pennsylvania]] within the [[Allegheny Reservoir]] just east of the [[Warren County, Pennsylvania|Warren]]-[[McKean County, Pennsylvania|McKean county]] line, approx. {{convert|10|mi|km}} northeast of [[Warren, Pennsylvania|Warren]].<ref>''Olean, NY,'' 1:100,000 Scale Topographic Map, USGS, 1986</ref>

It flows in a broad zigzag course generally southwest across [[Western Pennsylvania]]; first flowing southwest past Warren, [[Tidioute]], [[Tionesta, Pennsylvania|Tionesta]], [[Oil City, Pennsylvania|Oil City]], and [[Franklin, Pennsylvania|Franklin]], forming much of the northwestern boundary of [[Allegheny National Forest]]. South of Franklin it turns southeast across [[Clarion County, Pennsylvania|Clarion County]] in a [[meander]]ing course, then turns again southwest across [[Armstrong County, Pennsylvania|Armstrong County]], flowing past [[Kittanning, Pennsylvania|Kittanning]], [[Ford City, Pennsylvania|Ford City]], [[Clinton, Pennsylvania|Clinton]], and [[Freeport, Pennsylvania|Freeport]].<ref>''Warren, PA,'' 1:100,000 Scale Topographic Map, USGS, 1983</ref><ref>''Oil City, PA,'' 1:100,000 Scale Topographic Map, USGS, 1983</ref><ref>''Indiana, PA,'' 1:100,000 Scale Topographic Map, USGS, 1983</ref>

The river enters both [[Allegheny County, Pennsylvania|Allegheny]] and [[Westmoreland County, Pennsylvania|Westmoreland]] counties, the [[Greater Pittsburgh Region|Pittsburgh suburbs]], and the [[Pittsburgh|City of Pittsburgh]] from the northeast. It passes the [[North Side (Pittsburgh)|North Side]], [[downtown Pittsburgh]], and [[Point State Park]]. The Allegheny joins with the [[Monongahela River]] at the "Point" in downtown Pittsburgh to form the [[Ohio River]].<ref>''Pittsburg East'' and ''Pittsburg West'' 1:100,000 Scale Topographic Maps, USGS, 1986</ref>
