The Jewish Mob (also known by other names such as the Israeli Mafia, Israeli Mob, Hebrew Mob, or Kosher Nostra) is a type of organized crime syndicate, primarily consisting of Americans of Israeli descent, as well as Ashkenazi and Sephardi Jews. They have often worked closely with the American Mafia and sometimes even the Russian Mafia. Famous Jewish mobsters include Mickey Cohen, Bugsy Siegel, Meyer Lansky (of Ashkenazi bloodlines), and Frank Rosenthal (also of Ashkenazi bloodlines).
