The 4-Skins were a working class Oi! punk rock band from the East End of London, England. They formed in 1979 and disbanded in 1984.

Prior to the release of the band's debut single, "One Law For Them", The 4-Skins contributed songs to the first three Oi! compilation albums, alongside bands such as Cockney Rejects, Cock Sparrer, The Business and Angelic Upstarts.

Other well-known songs include: "Sorry", "Evil", "Chaos", "Plastic Gangsters" and "A.C.A.B." (All Coppers Are Bastards). Many of their songs dealt with violent topics, but the band has claimed they were discussing the realities of inner city life, not promoting violence. Other 4-Skins song topics include police harassment, political corruption, war and unemployment.

Most of the original four band members were or had been skinheads, thus the double meaning of the band's name. However, Steve Pear had a rockabilly style, and Hoxton Tom McCourt, who was a suedehead, was one of the leading faces in the mod revival.

Initially the band members had known each other from football (going to watch West Ham play), or from following bands such as Sham 69 and Menace.

The 4-Skins went through many personnel changes during their five-year existence, only bassist/songwriter 'Hoxton' Tom McCourt being present in every line-up of the band.

Notable former members include frontman of The Last Resort, Roi Pearce, and guitarist Paul Swain, who later joined white power band Skrewdriver.
