The Tramway of Clairvaux (French Tramway des Fours à Chaux) was a more than 5.8 km (3.6 mi) long narrow-gauge railway with a gauge of 600 mm (1 ft 11+5⁄8 in) in Ville-sous-la-Ferté near Clairvaux Abbey.

The main line ran on the départemental road D 396 in the Aube Valley to connect the hamlets Les Forges Saint Bernard, Le Four à Chaux and Clairvaux of the municipality Ville-sous-la-Ferté. It started at Clairvaux railway station on the Paris-Est–Mulhouse-Ville railway between Troyes and Culmont-Chalindrey.^[2] It passed the Usines du Pont Rouge, a subsidiary of the iron-frame bed manufacturer Etablissements Berl in Luxemburg, which are now owned by Regnier, a manufacturer of wooden seat panels.^{[3] [4]} It also passed the Hotel Saint Bernard, just opposite Clairvaux Abbey, which is now being used as a high-security prison, where it regularly stopped for refreshments and for taking photographs.^[5] From there it continued probably to other lime quarries and furnaces.
