Pennsylvania Route 34 (PA 34) is a 62-mile-long (100 km) state route located in southern Pennsylvania. The southern terminus of the route is at U.S. Route 15 Business (US 15 Bus.) in Gettysburg. The northern terminus is at US 11/US 15 south of Liverpool. PA 34 heads north from Gettysburg through farmland in northern Adams County, passing through Biglerville. The route crosses South Mountain into Cumberland County and reaches Mount Holly Springs, where it intersects PA 94. PA 34 heads north into the agricultural Cumberland Valley and heads north to Carlisle, where it has an interchange with Interstate 81 (I-81) in the southern part of town and intersects US 11/PA 74/PA 641 in the downtown area. The route continues north through more rural land and crosses Blue Mountain into Perry County, where it continues through the Ridge-and-Valley Appalachians, winding north to New Bloomfield. From here, PA 34 continues northeast to Newport, where it crosses the Juniata River and reaches an interchange with US 22/US 322, before heading to its terminus at US 11/US 15 near the Susquehanna River.

The section of the route between Mount Holly Springs and Carlisle became a turnpike called the Hanover and Carlisle Turnpike in 1812, which connected Carlisle to Hanover and served as a trade link between the Cumberland Valley and Baltimore. PA 34 was designated in 1928 to run from US 15 (now US 15 Bus.) in Gettysburg north to US 11 in Carlisle. The same year, the road between Carlisle and Mecks Corner was designated PA 33 while the road between Mecks Corner and Newport became part of PA 5. PA 34 was extended north from Carlisle to US 22 (Juniata Parkway) east of Newport in 1937, replacing those sections of PA 33 and PA 5. For a short time in the 1960s, PA 34 extended south from Gettysburg to US 15 in Fairplay along a former alignment of US 15 before being replaced by US 15 Bus. In 1970, the route was extended north from Newport to US 11/US 15 south of Liverpool.
