The Plynlimon and Hafan Tramway was a 2 ft 3 in (686 mm) gauge narrow gauge railway in Cardiganshire (now Sir Ceredigion) in Mid Wales. It ran from Llanfihangel (later renamed Llandre) station on the Cambrian Railways via the village of Talybont and the valley of the Afon Leri into the foothills of Plynlimon Fawr. It was built to serve the lead mines at Bwlch Glas and stone quarries around Hafan and opened in 1897, closing just two years later. The line was a little over 7 miles (11 km) long and despite running a short-lived passenger service, it served no communities of more than 100 people.
