The Unforgettable Fire is the fourth studio album by Irish rock band U2. It was produced by Brian Eno and Daniel Lanois, and released on 1 October 1984 by Island Records. The band wanted to pursue a new musical direction following the harder-hitting rock of their previous album, War (1983). As a result, they employed Eno and Lanois to produce and assist in their experimentation with a more ambient sound. The resulting change in direction was at the time the band's most dramatic. The album's title is a reference to "The Unforgettable Fire", an art exhibit about the atomic bombing of Hiroshima.

The album itself is signed by all members; Bono, The Edge, Larry Mullen JR & Adam Clayton.  The album was signed on February 27th, 2009 in London.
