The Brooklyn Camorra or New York Camorra is a term for a loose grouping of early-20th century organized crime groups that formed among Italian immigrants originating in Naples and the surrounding Campania region living in Greater New York, particularly in Brooklyn. In the early 20th century the criminal underworld of New York City consisted mainly of East Harlem-based Sicilians and groups of Neapolitans from Brooklyn, sometimes referred to as the Brooklyn Camorra, as Neapolitan organized crime was called the Camorra.
