Sauze d'Oulx (Italian pronunciation: [ˈsaudze ˈdulks]) is a town and comune in the Metropolitan City of Turin, Piedmont (northern Italy) located 80 km (50 miles) from Turin in the Val di Susa, at the foot of Monte Genevris (2,536 m or 8,320 feet).

Together with the villages of Pragelato, Sestriere, Claviere, Cesana Torinese, San Sicario and Montgenèvre, in France, it makes up the Via Lattea (Milky Way) skiing area.

Since the beginning of the 19th century, Sauze d'Oulx has been a destination for the Turin aristocracy, with its famous winter resort Sportinia and is still a skiing favourite because of its natural and accessible location.

After the fall of the Western Roman Empire, in the Middle Ages it was owned by the Novalesa Abbey and then by the provosts of Oulx.

After World War II, the town became an autonomous comune and the previous name was restored.
