London Calling is the third studio album by the English punk rock band The Clash. It was released in the United Kingdom on 14 December 1979 through CBS Records, and in the United States in January 1980 through Epic Records. The album represented a significant change in The Clash's musical style, which now featured major elements of ska, funk, pop, soul, jazz, rockabilly and reggae far more prominently than in their previous two albums.

The album's subject matter included social displacement, unemployment, racial conflict, drug use, and the responsibilities of adulthood. The album received unanimously positive reviews and was ranked at number eight on Rolling Stone's list of The 500 Greatest Albums of All Time in 2003. London Calling was a top ten album in the UK, and its lead single "London Calling" was a top 20 single. It has sold over five million copies worldwide, and was certified platinum in the United States.

After recording their second studio album Give 'Em Enough Rope (1978), the band separated from their manager Bernard Rhodes. This separation meant that the group had to leave their rehearsal studio in Camden Town and find another location to compose their music.
