"Timebomb" is a single from Chumbawamba's album Anarchy.

The album version of "Timebomb" combined elements of both the main single version and the "Techno Timebomb" remix, which was included as a B-side on this single.

The single also includes a cover of Leon Rosselson's 1975 song "The World Turned Upside Down", which was originally made popular by fellow English singer/songwriter Billy Bragg.

The song is about the 17th-century Digger movement's struggles against their landowners, and shares a lot of lyrical themes with the 1649 Gerrard Winstanley composition "Diggers' Song", which was also recorded by Chumbawamba on their English Rebel Songs 1381-1914 album, which also features another song called "The World Turned Upside Down".

The single spent one week on the chart, peaking at number 59.
