"Living in the Past" is a song by British progressive rock group Jethro Tull. It is one of its best-known songs, and it is notable for being written in the unusual 5/4 time signature. The 5/4 time signature is quickly noted from the beginning rhythmic bass pattern.

The single reached number 3 on the UK Singles Chart.

The song was originally recorded before the sessions for the 1969 album Stand Up, released in the same year as a stand-alone single to UK audiences while Jethro Tull finished its US tour. However, it became more popular after its 1972 release on the album of the same name, a compilation of the band's hits from that era. After its release on the album, it became the band's first Top 20 hit in the US, peaking at #11. The song was restored as a "bonus track" for the 2001 CD reissue of Stand Up (1969).

The song was first covered as an instrumental by CCS in 1970. Other cover versions include:
