The Koninklijke Muntschouwburg (de Munt) (Dutch), or le Théâtre Royal de la Monnaie (la Monnaie) (French) (both meaning Royal Theatre of the Mint) is a theatre in Brussels, Belgium.
Today the National Opera of Belgium, a federal institution, takes the name of the theatre in which it is housed. Therefore, "de Munt/la Monnaie" refers both to the structure as well as the opera company.
As Belgium's leading opera house it is one of the few cultural institutions which receives financial support from the federal government of Belgium. Other opera houses in Belgium, such as the Vlaamse Opera and the Opéra Royal de Wallonie, are funded by regional governments.
