Pennsylvania Route 181 (PA 181) is a 9-mile-long (14 km) north–south state route in York County in south central Pennsylvania. Its southern terminus is at Interstate 83 Business (I-83 Bus.) and U.S. Route 30 (US 30) in North York. Its northern terminus is at the southern terminus of PA 382 in York Haven. PA 181 heads north from US 30 as a four-lane divided highway concurrent with I-83 Bus to an interchange with I-83, where I-83 Bus. reaches its northern terminus. From here, PA 181 continues north as a two-lane undivided road through suburban areas, intersecting PA 238 in Emigsville and PA 921 in Manchester. The route runs through rural land before it comes to York Haven.

The road between York and York Haven was designated as part of PA 24 in 1928. In the 1950s, US 111 Alternate (US 111 Alt.) became concurrent with PA 24 between York and I-83/US 111 in North York. PA 181 was designated between PA 250 (now US 30) in North York and PA 382 in York Haven in 1961 after the north end of PA 24 was truncated to east of York; I-83 Bus. also replaced US 111 Alt. The section of the route between US 30 and I-83 became a divided highway in 2003.
