The Arc is a 128-kilometre-long (80 mi) river in the Savoie département of south-eastern France. It is a left tributary of the Isère River, which it joins at Chamousset, approximately 15 km (9.3 mi) downstream from Albertville. Its source is near the border with Italy, in the Graian Alps, northeast of Bonneval-sur-Arc. The valley of the Arc, the Maurienne, is an important transport artery between France and Italy.
