Owney "The Killer" Madden (played by Fredric Lehne) was a leading underworld figure in Manhattan, most notable for his involvement in organized crime during Prohibition. He also ran the famous Cotton Club and was a leading boxing promoter in the 1930s.

He seems to be an irrelevant character in the Boardwalk Empire world, serving to validate and introduce the fictional character Dr. Valentin Narcisse.
