Casino is a 1995 American epic crime film directed by Martin Scorsese, produced by Barbara De Fina and distributed by Universal Pictures. The film is based on the 1995 nonfiction book Casino: Love and Honor in Las Vegas by Nicholas Pileggi, who also co-wrote the screenplay for the film with Scorsese. It stars Robert De Niro, Sharon Stone, Joe Pesci, Don Rickles, Kevin Pollak and James Woods. The film marks the eighth collaboration between director Scorsese and De Niro.

Casino follows Sam "Ace" Rothstein (De Niro), a Jewish American gambling expert handicapper who is asked by the Chicago Outfit to oversee the day-to-day casino and hotel operations at the Tangiers Casino in Las Vegas. Supporting characters include Nicky Santoro (Pesci), a "made man" and friend of Sam, and Ginger McKenna (Stone), a streetwise chip hustler whom Sam marries and has a daughter with. The film details Sam's operation of the casino, the difficulties he confronts in his job, the Mafia's involvement with the casino, and the gradual breakdown of his relationships and standing, as Las Vegas changes over the years.

The primary characters are based on real people: Sam is inspired by the life of Frank Rosenthal, also known as "Lefty," who ran the Stardust, Fremont, Marina, and Hacienda casinos in Las Vegas for the Chicago Outfit from the early 1970s until 1981. Nicky and Ginger are based on mob enforcer Anthony Spilotro and former dancer and socialite Geri McGee, respectively.

Casino was released on November 22, 1995, to mostly positive critical reception, and was a worldwide box office success. Stone's performance was singled out for acclaim, earning her a Golden Globe Award for Best Actress in a Motion Picture – Drama and a nomination for the Academy Award for Best Actress.
