Leysin is a municipality of the canton of Vaud in the Aigle district of Switzerland. It is first mentioned around 1231–32 as Leissins, in 1352 as Leisins.

Located in the Vaudoises Alps, Leysin is a sunny alpine resort village at the eastern end of Lake Geneva in proximity to Montreux, Lausanne, and Geneva. In prior years, Leysin was known for its sanatoriums for tuberculosis; today its spectacular Alpine views across the Rhône Valley towards the Dents du Midi invite year-round mountain sports and recreation.
