The Dubois Brothers are nine of the ten sons of Napoléon Dubois. The gang were a French-Canadian organized crime group consisting of nine brothers, which operated mostly in Montreal in the 1950s to the mid-1980s.

A report by the Quebec Crime Commission called the gang "the most important criminal organization in Quebec," so vicious and strong that they were known to be feared by both outlaw motorcycle gangs and the Mafia.
