"Up All Night" is a song by American rock band Blink-182, released on July 14, 2011 as the lead single from the group's sixth studio album, Neighborhoods (2011). The song was the band's first single following a four-year hiatus. It was the first song the trio created upon their reformation in February 2009. Although the band wanted to release the track as a digital single in July 2009, they quickly decided it was too ambitious to complete before their fall reunion tour. The track generally grew heavier over the course of two-year recording process.
