Blink-182 is an American rock band formed in 1992 in Poway, California. 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.

The band's debut studio album, Cheshire Cat, was released in 1994. Their second studio album, Dude Ranch, came out in 1997. After years of independent recording and touring, including stints on the Warped Tour, the group signed to MCA Records. Their third and fourth albums—Enema of the State (1999) and Take Off Your Pants and Jacket (2001)—reached their furthest commercial success while their singles, "All the Small Things", "Dammit" and "What's My Age Again?" became hit songs and MTV staples. Later efforts, including an untitled album (2003), Neighborhoods (2011), and an EP Dogs Eating Dogs (2012), marked stylistic shifts. Hoppus is the only member to remain in the band throughout its entire history. DeLonge left the group twice, both times a decade apart, before returning once more. Founding drummer Scott Raynor recorded and toured with the group before being dismissed in 1998, thereafter being replaced by Barker. During DeLonge's absence from 2015 to 2022, the band included Alkaline Trio singer and guitarist Matt Skiba, with whom they recorded two albums, California (2016), and Nine (2019), and toured in support of both. Their ninth album, One More Time..., was released on October 20, 2023.

Blink-182's straightforward approach and simple arrangements, which helped initiate pop-punk's second mainstream rise, made them popular among generations of audiences. Worldwide, the group has sold 50 million albums and moved 15.3 million copies in the U.S.
