The Royal Conservatory of Liège (RCL) (French: Conservatoire royal de Liège) is a historic conservatory in Liège, Belgium. It is one of four conservatories in the French Community of Belgium that offers higher education courses in music and theatre.
Located at 29 Piercot Forgeur, the school's principal building was built in 1887 using a neoclassical design by architects Louis Boonen and Laurent Demany. Inside the building is a large concert hall, the Salle philharmonique de Liège, which has recently been entirely renovated. The hall is the major performance venue for the Orchestre Philharmonique de Liège.
