"A Huge Ever Growing Pulsating Brain That Rules from the Centre of the Ultraworld" is a single by the ambient house group The Orb. It was originally released in October 1989 and made the UK Singles Chart in 1990, peaking at #78. The 'Peel Session' version was also voted into #10 place in John Peel's 1990 Festive Fifty. In April 1991, it was released on the debut album The Orb's Adventures Beyond the Ultraworld. The title is taken from a sound effects track from Blake's 7 on BBC Sound Effects No. 26 - Sci-Fi Sound Effects titled "The Core, A Huge Evergrowing Pulsating Brain which Rules from the Centre of Ultraworld".

The song was featured on the soundtrack of the video game Grand Theft Auto: Episodes from Liberty City on the fictional in-game station Self-Actualization FM.

Throughout 1989, The Orb, along with Martin "Youth" Glover, developed the musical genre of ambient house through use of a diverse array of samples and recordings. The culmination of their musical work came when The Orb recorded a session for John Peel on BBC Radio 1. The track, then known as "Loving You", was largely improvisational and featured a wealth of sound effects and samples from science fiction radio plays, nature sounds, and Minnie Riperton's "Lovin' You". For its release as a single on record label Big Life, The Orb changed the title to "A Huge Ever Growing Pulsating Brain That Rules From the Centre of the Ultraworld". Upon the single's release, Riperton's management forced Big Life to remove the unlicensed Riperton sample, ensuring that only the initial first-week release of the single contained the original vocals of Minnie Riperton; subsequent pressings used vocals from a sound-alike.
