The Joshua Tree is the fifth studio album by Irish rock band U2. It was produced by Daniel Lanois and Brian Eno, and was released on 9 March 1987 on Island Records. In contrast to the ambient experimentation of their 1984 release, The Unforgettable Fire, the band aimed for a harder-hitting sound within the limitation of conventional song structures on The Joshua Tree. The album is influenced by American and Irish roots music, and through sociopolitically conscious lyrics embellished with spiritual imagery, it contrasts the group's antipathy for the "real America" with their fascination with the "mythical America".
Frequently listed among the greatest albums of all time, The Joshua Tree is one of the world's best-selling albums, with over 25 million copies sold. U2 commemorated the record's 20th anniversary with a remastered re-release, and its 30th anniversary with a concert tour and reissue. In 2014, it was selected for preservation in the US National Recording Registry, having been deemed "culturally, historically, or aesthetically significant" by the Library of Congress.
