"Invaders Must Die" is the eighteenth single released by British electronic band the Prodigy. It was released from the band's website as a free digital download on 26 November 2008. It was the first single from the album Invaders Must Die. The download was announced on 24 November, in a newsletter sent to fans, and first aired on Zane Lowe's Radio 1 show as his 'Hottest Record in the World' on 26 November. The song was co-produced by Does It Offend You, Yeah?'s James Rushent. Liam Howlett described this to the Dubai edition of Time Out as: "a very abrasive-sounding electronic track, kind of different to anything we've done before." Although not being a commercial single, the track charted at No. 49 on the UK Singles Chart on 1 March 2009, whilst the Chase & Status remix reached No. 53 on the Australian ARIA singles chart and No. 7 on the ARIA dance chart. On 30 November 2009, the re-amped version by Howlett was released as an EP with the B-side "Mescaline" and remixes of "Thunder".
