Pennsylvania Route 68 (PA 68) is a 90.036-mile-long (144.899 km) east–west state highway located in western Pennsylvania in the United States. The western terminus of the route is at the Ohio state line west of Glasgow, where PA 68 continues into Ohio as State Route 39 (SR 39). The eastern terminus is at U.S. Route 322 (US 322) in Clarion. The route runs southwest-northeast across Beaver, Butler, Armstrong, and Clarion counties. PA 68 follows the Ohio River between the Ohio border and Beaver, where it crosses the Beaver River into Rochester and heads northeast away from the Ohio River. The route runs through rural areas to Butler County, where it intersects Interstate 79 (I-79) in Zelienople before serving Evans City and Butler. PA 68 passes through a section of Armstrong County before crossing the Allegheny River into Clarion County. Here, the route passes through Rimersburg and Sligo before having an interchange with I-80 and continuing to its terminus in Clarion.

PA 68 was originally designated in 1927 to run from the Ohio border northeast to Clarion before continuing to US 6/US 120 in Kane. The route was extended northwest to PA 59 in Kinzua in 1935. The full length of the route was paved by 1940. The northern terminus was again moved to Kane in 1961, with PA 321 replacing most of the route north of there and the former northern terminus was inundated by the Allegheny Reservoir. The north end of PA 68 was cut back to its current location in 1970, with the road between Clarion and Kane becoming part of PA 66.
