"Moment of Surrender" is a song by rock band U2 and the third track on their 2009 album No Line on the Horizon. During the initial recording sessions for the album in 2007 in Fez, Morocco, the band wrote the song with producers Brian Eno and Daniel Lanois within a few hours. Together, they recorded the song in a single take; Eno called the song's recording "the most amazing studio experience [he's] ever had". According to him and Lanois, the track is the closest the band came to realising their original concept for the album of writing "future hymns". The seven-minute song features gospel-like vocals in the chorus, along with a predominantly organ- and piano-based musical accompaniment. Lyrically, the song is about a drug addict who is undergoing a crisis of faith.

No Line on the Horizon is the twelfth studio album by Irish rock band U2. It was produced by Brian Eno, Daniel Lanois, and Steve Lillywhite, and was released on 27 February 2009. It was the band's first record since How to Dismantle an Atomic Bomb (2004), marking the longest gap between studio albums of their career to that point. The band originally intended to release the songs as two EPs, but later combined the material into a single record. Photographer Anton Corbijn shot a companion film, Linear, which was released alongside the album and included with several special editions.
