Overbrook Farms is a neighborhood on the western edge of the West Philadelphia section of Philadelphia, Pennsylvania, United States. It is roughly bounded by City Avenue, 58th Street, Woodbine Avenue, and 66th Street at Morris Park. The neighborhood is bisected by Lancaster Avenue and the original Pennsylvania Railroad"main line". Today the rail line is used by both Amtrak passenger service and SEPTA's commuter Paoli/Thorndale Line. This region of Philadelphia and its suburbs were originally settled by Welsh immigrants, who purchased land from William Penn. Two of these farms contributed land for what became the Overbrook Farms neighborhood, which was developed beginning in 1892. The neighborhood is often incorrectly considered to be a sub-section of the larger and densely developed Overbrook neighborhood. Overbrook Farms was the first of several planned communities along the Main Line of the Pennsylvania Railroad. The Overbrook Farms Company was the developer; its officers had links to directors of the Girard and Drexel banks and the Penn Railroad. This planned community includes some of the first residential projects by the first graduating class of the University of Pennsylvania's architectural program. Overbrook Farms maintains the oldest continually operating neighborhood association in the United States, the Overbrook Farms Club. OFC sponsors an annual house tour each Spring. The neighborhood was designated as a National Historic District and is listed on the National Register of Historic Places. Its description and statement of significance can be found at , Historic Districts. Overbrook Farms, Its Historical Background, Growth and Community Life by Tello J. d'Apery, M.D. also provides a complete history of the area. A more recent development of smaller homes with modern incursions, called Greenhill Farms, is not included within the historic district. This development extends from 66th Street to 72nd Street. Bordered on three sides by Morris Park and on the west by City Avenue, it includes some original mansions built on Wistar Morris' gentleman's farm. The City Line Avenue Bridge was listed on the National Register of Historic Places in 1988.
