The Carnet Mondain (French for Social Notebook) of Belgium, is a directory featuring high society (nobility and upper bourgeoisie), Belgian or foreign, established in Belgium, as well as members of Belgian families established abroad. It is equivalent to the Social Register in the United States. Its tagline is "the Familial and Social Belgium" (French: la Belgique Familiale et Mondaine). It also publishes the coats of arms of these families, when armigerous.
