Oi Polloi are an anarcho-punk band from Scotland that formed around 1981, also notable for their contributions to the Scottish Gaelic punk sub-genre.

Oi Polloi's first studio recording was a demo entitled Destroi the System, which is believed to have been released in 1984 or 1985. After the now defunct music weekly Sounds gave their previous home-recorded demo a favourable review, demand increased for gigs further afield.

The band are supporters of Earth First! and uses the motto "No Compromise in Defence of Our Earth," which is an adaptation of Earth First!'s motto. They support direct action in defence of the environment, hunt sabotage, and resistance against racialism, sexism, homophobia, fascism and imperialism. They have recently started singing in Scottish Gaelic and use the language in day to day communications. They see the use of Gaelic and other endangered languages as important to maintaining the biocultural diversity of life.

Oi Polloi's was originally founded by Deek Allen and other friends from school. Their name Oi Polloi and their album Unite and Win (Punks and Skins) often gave the impression that they were a group of skinheads, or even anarchist skinheads. The band has never been a "skinhead band," but has had both skinhead and punk members who have emphasized unity between the two groups.
