The Ruthin and Cerrig-y-Drudion Railway was a proposed 1 ft 11+1⁄2 in (597 mm) narrow gauge railway that would have linked the towns of Ruthin and Cerrig-y-Drudion in Denbighshire, Wales. A bill was put before Parliament in 1873, promoting the railway, which was intended to meet the planned branch of the North Wales Narrow Gauge Railways from Beddgelert at Cerrig-y-Drudion.
