The Sicilian is a novel by American author Mario Puzo. Published in 1984 by Random House Publishing Group (ISBN 0-671-43564-7), it is based on the life of Sicilian bandit Salvatore Giuliano. It is set in the same universe as Puzo's most famous work, The Godfather (1969), and contains characters from The Godfather. It is regarded as The Godfather's literary sequel and is the second book in The Godfather novel series. It was adapted into a film in 1987, though all Godfather references were removed for copyright reasons in the film adaptation.
