The 60th Street Branch of the Pennsylvania Railroad was a 4.5-mile (7.2 km) branch line from South 58th Street in Philadelphia, Pennsylvania, to Hog Island, Pennsylvania. It was built in 1918 by the Philadelphia, Baltimore and Washington Railroad, a subsidiary of the PRR, and opened for service on August 20 of that year.
The line diverged from the PW&B's main line just north of Brill Interlocking, and bore southeast before curving southwest again.
