A Fistful of Dollars (Italian: Per un pugno di dollari), titled on-screen as Fistful of Dollars, is a 1964 Spaghetti Western film directed by Sergio Leone and starring Clint Eastwood in his first leading role, alongside Gian Maria Volontè, Marianne Koch, Wolfgang Lukschy, Sieghardt Rupp, José Calvo, Antonio Prieto, and Joseph Egger.

A Fistful of Dollars was filmed on a low budget (reported to be $200,000), and Eastwood was paid $15,000 for his role. Released in Italy in 1964 and then in the United States in 1967, it initiated the popularity of the spaghetti western film genre. It was followed by For a Few Dollars More and The Good, the Bad and the Ugly, also starring Eastwood. Collectively, the films are known as the "Dollars Trilogy", or "The Man With No Name Trilogy". The film has been identified as an unofficial remake of the Akira Kurosawa film Yojimbo (1961), which resulted in a successful lawsuit by Toho, the producers of Yojimbo

Sergio Leone took the plot and characters for his classic Western directly from Kurosawa's Yojimbo without authorization. According to one source, during the filming, Leone was "slaving over a moviola machine and copying Yojimbo, changing only the setting and details of the dialogue." Kurosawa himself wrote a letter to Leone, saying "[A Fistful of Dollars] is a very fine film, but it is my film" and demanding payment. The case was eventually settled out of court, with Kurosawa getting 15 percent of the Italian film's worldwide box office.
