Pic Chaussy is a mountain of the Vaud Alps , overlooking Les Diablerets to the south. On its northern side lies the Lac Lioson , whilst the Col des Mosses pass flanks its western side. To the east, a ridgeline connects to the peaks of the Châtillon and Le Tarent . Its summit reaches an altitude of 2,351 metres (7,713 ft).

The peak lies on the border between the municipalities of Ormont-Dessous and Ormont-Dessus , both in the Swiss canton of Vaud.

A gondola was built in 1962 from the Mosses pass to the summit, with a stop at the Lake Lioson.
