"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.

Blink-182 is an American rock band formed in Poway, California, in 1992. Their current and best-known line-up consists of bassist and vocalist Mark Hoppus, guitarist and vocalist Tom DeLonge, and drummer Travis Barker. Though their sound has diversified throughout their career, their musical style, described as pop-punk, blends catchy pop melodies with fast-paced punk rock. Their lyrics primarily focus on relationships, adolescent frustration, and maturity—or lack thereof. The group emerged from a suburban, Southern California skate punk scene and first gained notoriety for high-energy live shows and irreverent humour.
