"The Unforgettable Fire" is a song by rock band U2. The fourth song on their 1984 album The Unforgettable Fire, it was released as the album's second single in April 1985. The band cite an art exhibition by victims of the atomic bombings of Hiroshima and Nagasaki that was held at The Peace Museum in Chicago as inspiration for the song. It became the band's third Top 10 hit in the United Kingdom, reaching #6 on the UK Singles Chart and #8 on the Dutch singles chart, but it had yet to break them into the United States.
The song, like many tracks from The Unforgettable Fire, is an atmospheric composition, with ambient use of guitar and a string arrangement by Irish jazz musician Noel Kelehan.
