Aussois is a commune in the Vanoise Massif, in the Savoie department in the Auvergne-Rhône-Alpes region in south-eastern France. The village is on the border of France's first National Park, the Vanoise National Park.

At 8 km (5.0 mi) from Modane, it is ideally located in the Maurienne region with good transport links in and out of Lyon, Geneva, Grenoble and Chambéry. Aussois can also be reached from Turin via the Fréjus Road Tunnel, linking Bardonecchia in Italy and Modane.
