The North Side Gang, also known as the North Side Mob, was a multi-ethnic criminal organization within Chicago during the Prohibition era from the early 1920s to the mid-1930s. It was the principal rival of the South Side Gang, later known as the Chicago Outfit or Chicago Mafia, the predominantly Italian-American crime syndicate led by Johnny Torrio and Al Capone.
