Sestriere is a ski resort in Piedmont, Italy, a comune (municipality) of the Metropolitan City of Turin. It is situated in Val Susa, 17 km (11 mi) from the French border. Its name derives from Latin: ad petram sistrariam, that is at sixty Roman miles from Turin.

A ski resort is a resort developed for skiing, snowboarding, and other winter sports. In Europe, most ski resorts are towns or villages in or adjacent to a ski area – a mountainous area with pistes and a ski lift system. In North America, it is more common for ski areas to exist well away from towns, so ski resorts usually are destination resorts, often purpose-built and self-contained, where skiing is the main activity.
