"Fallen Angel" is a composition by English progressive rock band King Crimson. It is the second track on their seventh studio album, Red, released on 6 October 1974. The lyrics are a man's lament over the tragedy of his young brother, who joined a gang and was stabbed to death on the streets of New York City, sung with deep pathos by John Wetton. The band had never performed the song live since the time it was released on album, but it was finally performed live in Chicago in 2017.
