Piste Oreiller-Killy is a World Cup downhill ski course in France, at La Daille on Rocher de Bellevarde in Val d'Isere, Savoie. It debuted 60 years ago in 1966 and is named after ski legends Henri Oreiller and Jean-Claude Killy.

The course is about two kilometres (1.2 miles) down the road from "La face de Bellevarde", an extremely steep course designed by Bernhard Russi for the 1992 Winter Olympics.

Silvano Beltrametti's accident on the course in December 2001 led to safety improvements; blue lines were introduced in ski competitions, which led the way to the next poles.

Since opening in 1966, it is part of the "Critérium of the First Snow" (Critérium de la première neige), one of the oldest and most prestigious ski races in the world.

It was later named for alpine ski legends Henri Oreiller and Jean-Claude Killy, Olympic champions with strong ties to Val d'Isere.

Part of World Cup since its second season in 1968, it is one of the classic and most common hosts on the circuit for both genders.

It replaced cancelled events from Wengen (1990), Val Gardena (2000), Alta Badia (2000) and Beaver Creek (2001, 2008, 2016, 2020).

The course regularly hosts women's World Cup events; men's races moved to Bellevarde permanently in 2008, except when replacing previously cancelled events.
