Anthony John Soprano Sr. is a fictional character and the protagonist of the HBO crime drama television series The Sopranos, and portrayed by James Gandolfini. Soprano is a member of the Italian-American Mafia and, especially later in the series, acts as the boss of the fictional North Jersey DiMeo crime family. Usually referred to as Tony, the character was conceived by Sopranos creator and showrunner David Chase, who was also largely responsible for the character's story arc throughout the show's six seasons. Gandolfini was ultimately cast in the role ahead of several other actors including Steven Van Zandt and Michael Rispoli. The character is loosely based on stories from and about an assortment of La Cosa Nostra figures and especially on real-life New Jersey mobsters Ruggerio "Richie the Boot" Boiardo, boss of the North Jersey Genovese crime family, and Vincent "Vinny Ocean" Palermo, a former caporegime and de facto boss of the DeCavalcante crime family. Bobby Boriello and Mark Damiano II portrayed Tony Soprano as a child in one episode each and Danny Petrillo played the character as a teenager in three episodes. William Ludwig portrayed him as a child and James Gandolfini's son Michael Gandolfini portrayed a teenage version of the character in the 2021 prequel film The Many Saints of Newark.
