Cereal Killer Soundtrack is a studio album released by comedy metal/punk group Green Jellÿ on March 16, 1993. It is the soundtrack to their video album, Cereal Killer. It is the last album the band released under the name Green Jellö, as subsequent legal action over the trademark Jell-O led to the band being rebranded as Green Jellÿ, which would lead to later pressings of the album being reprinted with the new band name.

Green Jellÿ is an American comedy rock band formed in 1981. Originally named Green Jellö, the band changed its name due to legal pressure from Kraft Foods Inc., the owners of the Jell-O brand, who claimed that it was an infringement of their trademark.
