The Orchestre de Chambre de Lausanne (Lausanne Chamber Orchestra) is a Swiss chamber orchestra based in Lausanne, Switzerland.
The Lausanne Chamber Orchestra (OCL) performs some 100 concerts each season at the Salle Métropole in Lausanne, its place of residence, as well as throughout Switzerland and abroad. Thus the ensemble could be heard at the Théâtre des Champs-Elysées and at the Salle Pleyel in Paris, at the Alte Oper in Frankfort, at the Accademia Nazionale di Santa Cecilia in Rome, at the Musikverein in Vienna, as well as at festivals such as the BBC Proms in London, the George Enescu Festival in Bucharest and the Rheingau Festival.
Founded in 1942 by Victor Desarzens, the OCL has collaborated with eminent international artists such as conductors Ernest Ansermet, Günter Wand, Paul Hindemith, Charles Dutoit, Neeme Järvi and Jeffrey Tate, as well as with soloists such as Isaac Stern, Radu Lupu and Martha Argerich. During the course of its nearly 70 years of existence the orchestra has been led by only five artistic directors: Victor Desarzens (1942–1973), Armin Jordan (1973–1985), Lawrence Foster (1985–1990), Jesús López Cobos (1990–2000) and Christian Zacharias (2000–2013).
