The Potomac, Fredericksburg, and Piedmont Railroad (PF&P) was a 3 ft (914 mm) narrow gauge short-line railroad in central Virginia that operated between Fredericksburg and Orange, Virginia. It operated until 1926, when its track was sold. A one-mile portion of the former PF&P line continued to be operated as the Virginia Central Railway until the early 1980s. The track has since been removed.
Portions of the East Coast Greenway run along the former railway.
