Salvatore "Sal" Tessio is a fictional character in Mario Puzo's 1969 novel The Godfather, as well as two of the films based on it: The Godfather (1972) and The Godfather Part II (1974). His given name was created for the films; in the novel he is referred to only as "Tessio". In the film The Godfather, Tessio was portrayed by Abe Vigoda. In The Godfather Part II, John Aprea portrayed the younger Tessio, while Vigoda reprised the role in a flashback, set in late 1941, at the end of the film.
