Pennsylvania Route 380 (officially, SR 400 because of I-380 elsewhere in Pennsylvania), also known as J.F. Bonetto Memorial Highway and within the city of Pittsburgh Bigelow Boulevard, Baum Boulevard and Frankstown Road, is a 32.80-mile-long (52.8 km) state highway in western portions of the U.S. state of Pennsylvania. The western terminus of the route is at Interstate 579 in downtown Pittsburgh near PPG Paints Arena. The eastern terminus is at Pennsylvania Route 286 in Bell Township, near the hamlet of Wakena.

When it was first assigned in the late 1920s, PA 380 occupied only the portion of its modern alignment between PA 286 in Murrysville and PA 286 west of Saltsburg. It was later extended westward over the former routing of PA 80 to Pittsburgh.
