The Prix de Lausanne is an international dance competition held annually in Lausanne, Switzerland. The competition is for young dancers seeking to pursue a professional career in classical ballet, and many former prize winners of the competition are now leading stars with major ballet companies around the world. The competition is managed by a non-profit foundation organised by the Fondation en faveur de l'Art chorégraphique and is maintained by various sponsors, patrons and donors.

Lausanne is the capital and largest city of the Swiss French-speaking canton of Vaud. It is a hilly city situated on the shores of Lake Geneva, about halfway between the Jura Mountains and the Alps, and facing the French town of Évian-les-Bains across the lake. Lausanne is located 62 kilometres northeast of Geneva, the nearest major city.
