"Integral" is a song by English synth-pop duo Pet Shop Boys from their ninth studio album, Fundamental (2006). The lyrics address the Identity Cards Act 2006 in the UK, which the duo opposed.

A remixed version of the song was released on 8 October 2007 as a download-only single to promote the duo's fourth remix album, Disco 4 (2007). The single peaked at number 197 on the UK Singles Chart.
