Rock Around the Clock is the third album of rock and roll music by Bill Haley and His Comets. Released by Decca Records in December 1955 it was, like the two albums that preceded it, a compilation album of previously issued singles. All of the album's contents had in fact been previously issued by Decca earlier in 1955 on the album Shake, Rattle and Roll. Unlike the previous release, which was in the 10-inch format, the new album was a full 12-inch release and included additional tracks from 1955. It was also the first Haley album to make the Billboard charts, and was one of the first album releases of the rock and roll genre to do so.

Bill Haley & His Comets was an American rock and roll band formed in 1947 and continuing until Haley's death in 1981. The band was also known as Bill Haley and the Comets and Bill Haley's Comets. From late 1954 to late 1956, the group recorded nine Top 20 singles, one of which was number one and three that were Top Ten. The single "Rock Around the Clock" was the best-selling rock single in the history of the genre and maintained that position for several years.
