Pennsylvania Route 88 (PA 88) is a 68-mile-long (109 km) north–south state highway located in southwestern Pennsylvania. The southern terminus of the route is at U.S. Route 119 (US 119) in Point Marion less than 2 miles (3 km) from the Pennsylvania-West Virginia border. The northern terminus is at PA 51 in Pittsburgh. PA 88 runs parallel to the Monongahela River for almost its entire length.
Signed in 1927, PA 88 is one of the oldest state highways in Pennsylvania. For a brief period between 1927 and 1928, the route followed the Perry Highway between Pittsburgh and Erie. In 1928, the Perry Highway became US 19.
