Pennsylvania Route 233 (PA 233) is a 53-mile-long (85 km) north–south state highway in south central Pennsylvania. It runs from PA 997 in Mont Alto north to PA 274 in Green Park. PA 233 heads northeast from Mont Alto through forested areas in the South Mountain range, where it runs through Mont Alto and Caledonia state parks and has an intersection with U.S. Route 30 (US 30). After heading northwest out of the mountains, the route continues into the agricultural Cumberland Valley, where it intersects Interstate 81 (I-81) and US 11 and crosses PA 641 in Newville. PA 233 crosses Blue Mountain into Perry County near Colonel Denning State Park and heads northeast to Landisburg, where it intersects PA 850 and turns north to continue to its terminus.

PA 233 was designated in 1928 to run from US 11 (now PA 174) in Dickinson north to PA 33 (now PA 34) in Dromgold, heading north to Landisburg before turning to the east. The road between Landisburg and Green Park became part of PA 74 the same year. In 1937, PA 233 was extended south from Dickinson to PA 997 in Mont Alto. The route was realigned to head north from Landisburg to PA 17 in Ickesburg in the 1930s, replacing a section of PA 74; the former alignment between Landisburg and Dromgold became part of PA 850. In the 1940s, the north end of PA 233 was cut back to PA 274 in Green Park, with most of the route north of there becoming an extended PA 74.
