"Crazy Little Thing Called Love" is a song by the British rock band Queen. Written by Freddie Mercury in 1979, the track appears on their 1980 album The Game. It reached number two in the UK singles chart in late 1979, before becoming the group's first number-one single on the US Billboard Hot 100 in early 1980, where it remained for four consecutive weeks. The song was Queen's final single release of the 1970s and was later included on their 1981 compilation album Greatest Hits.
