The Sopranos is an American crime drama television series created by David Chase. The series revolves around Tony Soprano (James Gandolfini), a New Jersey-based Italian-American mobster who struggles to balance his family life with his role as the leader of a criminal organization, which he reluctantly explores during therapy sessions with psychiatrist Jennifer Melfi (Lorraine Bracco). The series also features Tony's various family members, Mafia colleagues, and rivals in prominent roles—most notably his wife Carmela (Edie Falco) and his protégé and distant cousin Christopher Moltisanti (Michael Imperioli).

Having been greenlit in 1997, the series was broadcast on HBO from January 10, 1999, to June 10, 2007, spanning six seasons and 86 episodes. Broadcast syndication followed in the United States and internationally. The Sopranos was produced by HBO, Chase Films, and Brad Grey Television. It was primarily filmed at Silvercup Studios in New York City, with some on-location filming in New Jersey. The executive producers throughout the show's run were Chase, Brad Grey, Robin Green, Mitchell Burgess, Ilene S. Landress, Terence Winter, and Matthew Weiner.

Widely regarded as one of the greatest and most influential television series of all time, The Sopranos has been credited with kickstarting the Second Golden Age of Television. The series won multiple awards, including Peabody Awards for its first two seasons, 21 Primetime Emmy Awards, and five Golden Globe Awards. It has been the subject of critical analysis, controversy, and parody; it has also spawned books, a video game, soundtrack albums, podcasts, and merchandise. Several members of the show's cast and crew were largely unknown to the public when it began, but have since had successful careers. In 2013, the Writers Guild of America named The Sopranos the best-written TV series of all time, while TV Guide ranked it the best television series of all time. In 2016 and 2022, the series came in first place on the Rolling Stone list of the 100 greatest TV shows of all time.

In March 2018, New Line Cinema announced that they had purchased a film detailing the show's background story, set in the 1960s and 1970s during and after the Newark riots. The film, The Many Saints of Newark (2021), was written by Chase and Lawrence Konner and directed by Alan Taylor. It starred Gandolfini's son Michael Gandolfini as a young Tony Soprano.
