The Chestnut Hill East Branch is a railway line in Pennsylvania. It runs 5.5 miles (8.9 km) from a junction with the SEPTA Main Line in Nicetown–Tioga, a neighborhood in Philadelphia, to Chestnut Hill, Philadelphia. The oldest part of it was built in 1832 by the Philadelphia, Germantown and Norristown Railroad. It was part of the Reading Company system from 1870 until 1976. Today it is owned by SEPTA and hosts the Chestnut Hill East Line commuter rail service. The line runs roughly parallel to the Chestnut Hill West Branch, formerly of the Pennsylvania Railroad.
