The Fréjus Rail Tunnel is a rail tunnel of 13.7 km length in the European Alps, carrying the Turin–Modane railway through Mont Cenis to an end-on connection with the Culoz–Modane railway and linking Bardonecchia in Italy to Modane in France. Its mean altitude is 1,123 m and it passes beneath the Pointe du Fréjus and the Col du Fréjus.
The Fréjus tunnel remains an important link in the connection between Rome and Paris, via Turin and Chambéry. Following the development of car and truck transportation, the Fréjus Road Tunnel was built along the same path from 1974 to 1980. A future high-speed rail tunnel to improve transit capacity between France and Italy is being planned at a much lower elevation as part of the Turin–Lyon high-speed railway project.
