The Chester Creek Branch was a 7.25-mile (11.67 km) railroad line that operated in southern Delaware County, Pennsylvania, from 1869 to 1972. Built by the Chester Creek Railroad, it was originally operated and leased by the Philadelphia and Baltimore Central Railroad, then by a subsidiary of the Pennsylvania Railroad, and finally, for a few years, by PRR successor Penn Central. It connected the Lamokin Street station in Chester to Lenni station in Middletown Township.
