Pennsylvania Route 174 (PA 174) is a 28-mile-long (45 km) state highway located in Cumberland County, Pennsylvania. The western terminus is at U.S. Route 11 (US 11)/PA 533 in Shippensburg. The eastern terminus is at PA 641 in Monroe Township. PA 174 is a two-lane undivided road that runs through farmland in southern Cumberland County. The route heads east from Shippensburg and comes to an interchange with Interstate 81 (I-81). PA 174 continues through rural land, intersecting PA 233 in Dickinson, PA 465 in Mooredale, and PA 34 north of Mount Holly Springs before passing through Boiling Springs. From here, the route heads northeast and crosses PA 74 before coming to its end at PA 641 west of Mechanicsburg.

The portion of the present-day route west of PA 465 in Mooredale became part of US 11 and PA 13 in 1926, with the latter designation removed two years later. PA 174 was designated in 1928 between Boiling Springs and PA 641 west of Mechanicsburg. In 1937, the route was extended west from Boiling Springs to US 11 in Mooredale. US 11 and PA 33 switched alignments between Shippensburg and Carlisle in 1941, with PA 33 designated onto the present-day route west of Mooredale. In the 1960s, PA 33 was decommissioned and PA 174 was extended west to US 11/PA 533 in Shippensburg.
