Pennsylvania Route 112 (known formerly by the Pennsylvania Department of Highways as SR 0112) was a 4.75-mile (7.64 km) long state highway located in Delaware and Chester counties in Pennsylvania. Running along current day Cheyney Road, PA 112 began at an intersection with U.S. Route 1 in Markham, headed northward, and terminated at an intersection with Pennsylvania Route 926 in the community of Tanguy.

PA 112 was assigned in the commonwealth's numbering of state highways in 1928. The route remained intact for thirteen years, when, in 1941, the highway was extended southward to U.S. Route 322 south of Markham. The route remained for another five years, when the route was removed from the state highway system completely.
