Agnostic Front is an American hardcore punk band from New York City.Founded in 1980, the band is considered an important influence to the New York hardcore scene, as well as for pioneering the crossover thrash genre.

Formed in 1980 with Vincent "Vinnie Stigma" Capuccio (formerly of the Eliminators) on lead guitar, with Diego on bass, Rob Krekus on drums and John Watson on vocals. Despite being billed at their first concert as the Zoo Crew, Stigma introduced them as Agnostic Front, saying that the poster had been made prior to deciding on the name. The band went through several singers, including Jimmy "The Mad Russian". Although never having spoken to him before, Stigma told some of his friends to ask Roger Miret (former bass player of The Psychos) if he wanted to be the vocalist of Agnostic Front, because he liked his style of slam dancing. They soon added Ray Barbieri, aka Raybeez, on drums and Adam Mucci on bass. Their debut EP, United Blood, released in 1983 on an indie label, has since become a collector's item.

During its initial phase, the band consisted entirely of skinheads. Although this would change over time, Agnostic Front would continue to feature skinheads as part of their line-up. This led to a belief among some that the band espoused ultra-nationalist or fascist politics, an assertion denied by vocalist Roger Miret in a 1985 Flipside interview: "...We're skinheads. And the skinheads in England have a very bad name like with the fascists and stuff like that. But this is America not England. Just because the skinheads are fascists over there doesn't mean we got to grow our hair out if we don't feel like it.... We love our country — but not necessarily how our government works."
