The Salle Favart, officially the Théâtre de l'Opéra-Comique, is a Paris opera house and theatre, the current home of the Opéra-Comique. It was built from 1893 to 1898 in a neo-Baroque style to the designs of the French architect Louis Bernier and is located on the Place Boïeldieu just south of the Boulevard des Italiens.
