Anthony John Spilotro (May 19, 1938 – June 14, 1986), nicknamed "Tony the Ant", was an American mobster and enforcer for the Chicago Outfit in Las Vegas, Nevada, during the 1970s and 80s.
Spilotro's job was to protect and oversee the Outfit's illegal casino profits (the "skim"), when some of the casinos were run by Frank Rosenthal; replacing Outfit member Marshall Caifano in Las Vegas.Spilotro eventually ran afoul of his organized crime overseers who disapproved of his handling Las Vegas affairs, and who then arranged his murder in 1986.
Spilotro served as the basis for the character Nicky Santoro in Martin Scorsese's mafia classic, Casino (1995).
