The Orchestre symphonique de Québec (OSQ; English, Quebec Symphony Orchestra) is a Canadian symphony orchestra based in Quebec City. Founded in 1902 as the Société symphonique de Québec, the OSQ is the oldest active Canadian orchestra. Joseph Vézina was the OSQ's first music director, from 1902 to 1924. In 1942 the orchestra merged with rival orchestra Cercle philharmonique de Québec (founded 1936), at which time it changed its name to the Orchestre Symphonique de Québec.
