The Tour Ronde () is a mountain in the Mont Blanc massif of the Alps, situated on the border between France and Italy. It is a prominent mountain, some 3.5 km north-east of Mont Blanc, but is effectively part of a continuation of the south eastern spur of Mont Maudit (l'Arete de la Brenva) which forms a frontier ridge between the two countries. It is easily accessible to mountaineers and provides not only a very good viewpoint from its summit of the Brenva face and the major peaks on the southern side of Mont Blanc, but it also offers a popular introduction to alpine climbing of all grades, including a north face ascent.
