Donnie Brasco is a 1997 American crime drama film directed by Mike Newell, and starring Al Pacino and Johnny Depp. Michael Madsen, Bruno Kirby, James Russo, and Anne Heche appeared in supporting roles. The film, written by Paul Attanasio, is based on the 1988 nonfiction book Donnie Brasco: My Undercover Life in the Mafia by Joseph D. Pistone and Richard Woodley.

Benjamin "Lefty" Ruggiero was an American mobster in the Bonanno crime family. He is well known for his friendship and mentorship of FBI undercover agent Joseph D. Pistone, who Ruggiero knew as Donnie Brasco. When Pistone's operation was ended on July 26, 1981, the FBI intercepted and arrested Ruggiero on August 29, 1981. In November 1982, Ruggiero was sentenced to 15 years in prison for racketeering conspiracy; he was released in April 1993 before his death from cancer.
