The Dollars Trilogy (Italian: Trilogia del dollaro), also known as the Man with No Name Trilogy, is a film series consisting of three Spaghetti Western films directed by Sergio Leone. The films are titled A Fistful of Dollars (1964), For a Few Dollars More (1965) and The Good, the Bad and the Ugly (1966). They were distributed by United Artists.

The only actors to appear in all three movies besides Eastwood are Mario Brega, Aldo Sambrell, Benito Stefanelli and Lorenzo Robledo. Four other actors each appear twice in the trilogy, playing different characters: Lee Van Cleef, Gian Maria Volontè, Luigi Pistilli, and Joseph Egger.

The series has become known for establishing the Spaghetti Western genre, and inspiring the creation of many more Spaghetti Western films. The three films are consistently listed among the best rated Western films of all time.

Although it was not Leone's intention, the three movies came to be considered a trilogy following the exploits of the same so-called "Man with No Name" (portrayed by Clint Eastwood, wearing the same clothes and acting with the same mannerisms). The "Man with No Name" concept was invented by the American distributor United Artists, looking for a strong angle to sell the movies as a trilogy.
