Giuseppe Greco was a hitman and high-ranking member of the Sicilian Mafia. A number of sources refer to him exclusively as Pino Greco, although Giuseppe was his Christian name; Pino is a frequent abbreviation of the name Giuseppe.

Contract killing is a form of murder or assassination in which one party hires another party to kill a targeted person or people. It involves an agreement which includes some form of compensation, monetary or otherwise. It is an illegal agreement. Either party may be a person, group, or organization. Contract killing has been associated with organized crime, government conspiracies, dictatorships, and vendettas. For example, in the United States, the Italian- and Jewish-American organized crime gang Murder, Inc. committed hundreds of murders on behalf of the National Crime Syndicate during the 1930s and '40s.
