Pennsylvania Route 103 (abbreviated PA Route 103 or PA 103, officially State Route 103 or SR 103) is a 30.8-mile (49.57 km) long north–south designated state route in the Commonwealth of Pennsylvania. Its primary course is along the south/east side of the Juniata River, while U.S. Route 522 runs along the opposite side. PA 103's southern terminus is an at-grade intersection with US 522 at Allenport in Shirley Township, a bit south of US 522's bridge across the Juniata River in Mount Union. Its northern terminus is an intersection with US 22 Business in Lewistown. It intersects the northern terminus of PA 333 just south of Juniata Terrace.
Following the passage of the Sproul Road Bill in 1911, the forerunner to PA 103 was Route 33, which ran from Lewistown to Huntingdon. By 1915, however, Route 33 was moved across the Juniata River to the current location of US 22/522, leaving the route unnumbered once again.
Under the 1925 numbering system, PA 103 was a spur route of the original PA 3, the William Penn Highway. Its course journeyed from McVeytown to Juniata Terrace. At that time, the original route twisted through the town of Granville and crossed the Juniata River between Mattawanna and McVeytown.
By 1936, the original PA 3 had been eliminated. That same year, PA 103's southern terminus was moved from its intersection with US 22/522 in McVeytown to its current location in Allenport. Since 1941, PA 103's most of its course has been unchanged, as it continues to curve through Mattawanna, but bypasses the center of Granville. In the early-1980s, the northern terminus was moved to the intersection with US 22/522 in Lewistown following the reconstruction of the bridge crossing the Conrail tracks near the Lewistown Station.
