The Philadelphia, Germantown and Chestnut Hill Railroad was a railway company in the United States.

A subsidiary of the Pennsylvania Railroad, it was incorporated in 1883 to construct a line to the west side of the Chestnut Hill neighborhood in Philadelphia.

The Philadelphia, Germantown and Chestnut Hill Railroad was the brainchild of Henry H. Houston, a Philadelphia businessman who had invested in land on the west side of the Chestnut Hill neighborhood.

The project was then known as the Germantown, Norristown and Phoenixville Railroad; the Philadelphia, Germantown and Chestnut Hill Railroad name was adopted in 1882 when the planned extension to Norristown and Phoenixville were dropped.

The line, running 6.75 miles (10.86 km) to Chestnut Hill West, opened on June 11, 1884.
