Horse Rotorvator is the second studio album by English experimental music group Coil, released in 1986.

Coil were an English experimental music group formed in 1982 in London and dissolved in 2005. Initially envisioned as a solo project by musician John Balance, Coil evolved into a full-time project with the addition of his partner and Psychic TV bandmate Peter Christopherson. Coil's work explored themes related to the occult, sexuality, alchemy, and drugs while influencing genres such as gothic rock, neofolk and dark ambient. AllMusic called the group "one of the most beloved, mythologized groups to emerge from the British post-industrial scene."
