The Killing Fields is the 10th record album by Mike Oldfield, released in 1984. It was the soundtrack album for the film of the same name and it is the only full score written by Oldfield. The music was orchestrated by David Bedford. All tracks written by Mike Oldfield, except "The Year Zero" (David Bedford) and "Étude"(Francisco Tárrega, arranged by Oldfield).

Though Oldfield's music had been used in films before, this was the first time he had written specifically for film, and so far the only time. Oldfield composed the album on a Fairlight CMI.

Like many movies, the album is not a comprehensive record of all the Oldfield soundtrack music used in the film. Most notably, the music accompanying the darkroom sequence does not feature on the album. The single from the album, "Étude", is taken from the Francisco Tarrega piece "Recuerdos de la Alhambra".

Oldfield spent six months working on the score for The Killing Fields before going on tour, but when Oldfield returned the producers of the film asked for more music to be written, prompting Oldfield to ask for the use of an orchestra and a choir; three months later the score was finished. It was released just a few months after Oldfield's previous album, Discovery.
