"Rock Around the Clock" is a rock and roll song in the 12-bar blues format written by Max C. Freedman and James E. Myers (the latter being under the pseudonym "Jimmy De Knight") in 1952. The best-known and most successful rendition was recorded by Bill Haley & His Comets in 1954 for American Decca. It was a number one single on both the United States and United Kingdom charts and also reentered the UK Singles Chart in the 1960s and 1970s.

Haley's recording nevertheless became an anthem for rebellious 1950s youth and is widely considered to be the song that, more than any other, brought rock and roll into mainstream culture around the world. The song is ranked No. 158 on the Rolling Stone magazine's list of The 500 Greatest Songs of All Time.
