Abraham "Bo" Weinberg (1897-September 9, 1935?) was a Russian-born New York mobster and chief lieutenant of Dutch Schultz. Recruited by Schultz as he expanded his bootlegging operations into Manhattan during Prohibition, he and his brother George Weinberg would become his top gunmen during the Manhattan Bootleg Wars and was a later suspect in the gangland slayings of Jack "Legs" Diamond and Vincent "Mad Dog" Coll and Salvatore Maranzano.
