Pennsylvania Route 412 (PA 412) is a 17.75-mile-long (28.57 km) north–south state route located in Bucks and Northampton counties in southeastern Pennsylvania. Its southern terminus is at PA 611 in the Nockamixon Township community of Harrow. Its northern terminus is at PA 378 in Bethlehem.

The route passes through rural areas in northern Bucks County, forming a concurrency with PA 212 in the Springtown area. From there, PA 412 continues into Northampton County and passes through Hellertown before coming to an interchange with Interstate 78 (I-78) and heading into Bethlehem. In Bethlehem, PA 412 passes the former Bethlehem Steel site and runs through the South Side neighborhood.

PA 412 was originally part of the 18th-century Durham Road that ran through Bucks County and north into the Lehigh Valley. The route was first designated by 1927 between PA 212 in Springtown and PA 12 in Bethlehem. PA 412 was extended south to U.S. Route 611 (US 611) in Harrow by 1930. The route was realigned through the South Side of Bethlehem in the 1980s.
