Bretaye (or Col de Bretaye) is a high mountain pass of the Swiss Alps, located above Villars-sur-Ollon in the canton of Vaud. The pass (1,806 m) is connected to Villars by the Bex–Villars–Bretaye railway, which is the second highest railway of the canton after the Montreux–Glion–Rochers-de-Naye railway. In winter, Bretaye is the main ski area of Villars and a chairlift leads to the summit of Le Chamossaire (2,112 m).
