Villeneuve is a town and comune in the Aosta Valley, a region of northwestern Italy. It is located along the Dora Baltea river, roughly 10 kilometres (6 mi) west of the city of Aosta, on the road leading toward Courmayeur and the Mont Blanc Tunnel.
Near the town lie the ruins of the medieval castle known as Châtel-Argent, a site associated with the area's history. The comune's position along the Dora Baltea places it within the valley's main route through the Alps.
