The music of Star Wars consists of the scores written for all six Star Wars films by composer John Williams from 1977 to 1983 for the Original Trilogy, and 1999 to 2005 for the Prequel Trilogy. Williams' scores for the double trilogy count among the most widely known and popular contributions to modern film music. Additionally, music for Star Wars: The Clone Wars was written by Kevin Kiner, and further music has been composed for Star Wars video games and works in other media.

The scores utilize an eclectic variety of musical styles, many culled from the Late Romantic idiom of Richard Strauss and his contemporaries that itself was incorporated into the Golden Age Hollywood scores of Erich Korngold and Max Steiner. While several obvious nods to Gustav Holst, William Walton and Igor Stravinsky exist in the score to Episode IV, Williams relied less and less on classical references in the latter five scores, incorporating more strains of modernist orchestral writing with each progressive score. The reasons for Williams' tapping of a familiar Romantic idiom are known to involve Lucas' desire to ground the otherwise strange and fantastic setting in well-known, audience-accessible music. Indeed, Lucas maintains much of the trilogy's success relies not on advanced visual effects, but on the simple, direct emotional appeal of its plot, characters and, importantly, music.

Star Wars is an American epic space opera film series created by George Lucas. The first film in the series was originally released on May 25, 1977, under the title Star Wars, by 20th Century Fox, and became a worldwide pop culture phenomenon, followed by two sequels, released at three-year intervals. Sixteen years after the release of the trilogy's final film, the first in a new prequel trilogy of films was released. The three films were also released at three-year intervals, with the final film released on May 19, 2005.

Currently, the overall box office revenue generated by the Star Wars films has totaled at $4.49 billion, making it the third-highest-grossing film series, behind only the Harry Potter and James Bond films.

The Star Wars film series has spawned a media franchise including books, television series, video games, and comic books. These supplements to the film trilogies comprise the Star Wars Expanded Universe, and have resulted in significant development of the series' fictional universe. These media kept the franchise going in the interim between the film trilogies. In 2008, Star Wars: The Clone Wars was released to theaters as the first-ever worldwide theatrical Star Wars film outside of the main trilogies. It was the franchise's first animated film, and was intended as an introduction to the Expanded Universe television series of the same name, a 3D CGI animated series based on a previous 2D animated series of a similar name.
