The Godfather is a crime novel written by Mario Puzo, originally published in 1969 by G. P. Putnam’s Sons. It details the story of a fictitious Sicilian Mafia family based in New York City and headed by Don Vito Corleone, who became synonymous with the Italian Mafia.

The novel covers the years 1945 to 1955, and also provides the back story of Vito Corleone from early childhood to adulthood. The book introduced Italian criminal terms like consigliere, caporegime, Cosa Nostra, and omertà to an English-speaking audience.

It formed the basis for a 1972 film of the same name. Two film sequels, including new contributions by Puzo himself, were made in 1974 and 1990. The first and second films are widely considered to be two of the greatest films of all time.
