Pennsylvania Route 873 (PA 873) is a north-south, two-lane road in the Lehigh Valley region of Pennsylvania, mainly located in northern Lehigh County with a small section in Northampton County. Its southern terminus is at PA 309 in Schnecksville. Its northern terminus is at PA 248 in the Lehigh Township hamlet of Weiders Crossing. The route runs through rural areas in northern Lehigh County, intersecting the western terminus of PA 329 in Neffs. PA 873 passes through Slatington as Main Street before it crosses the Lehigh River into Northampton County and immediately reaches its northern terminus south of Lehigh Gap in Blue Mountain.

The road between Schnecksville and Lehigh Gap was originally designated part of Legislative Route 163 in 1911. This section of road became part of U.S. Route 309 (US 309) when the U.S. Highway System was established in 1926. In the late 1920s, PA 22 and PA 130 were briefly marked concurrent with US 309 at different times. In the 1950s, US 309 was moved to a new alignment to the west, and part of PA 29 was designated onto the road between Schnecksville and Lehigh Gap. PA 873 was designated onto this road on May 9, 1966 after PA 29 was split into two segments.
