Circus music (also known as carnival music) is any sort of music that is played to accompany a circus, and also music written that emulates its general style. Popular music would also often get arranged for the circus band, as well as waltzes, foxtrots and other dances.

Although circuses have been in existence since the time of the ancient Romans, circus music first started as a performance by a fiddler or a flutist. It was not until the twentieth century that circus music was performed by big bands. The first modern circus director and performer was Philip Astley (1742–1814), a veteran of the Seven Years' War and a skilled equestrian. With his horsemanship skills and the addition of jugglers, acrobats, and clowns, Astley opened Paris's first circus in 1782. The first known composer of circus music was Charles Dibdin (1745–1814). He was partners with Astley and was also the one who financed the theatre used for the royal circus. Dibdin was a very well known composer in his time and had written hundreds of works before he decided to join Astley to work for the circus. He wrote all of the pieces used in the circus, which were mostly intermezzos or comedy pieces. An ensemble of approximately sixty children was used as singers and dancers to perform the many pieces that he wrote for the circus, such as "The Graces", "Clump and Cudden", and "Pandora", which was arguably the most famous piece that was used in the circus because it was originally used in a popular puppet show that mocked contemporary figures of the time.
