In Norse mythology, Ragnarök is a series of future events, including a great battle foretold to ultimately result in the death of a number of major figures (including the gods Odin, Thor, Týr, Freyr, Heimdallr, and Loki), the occurrence of various natural disasters, and the subsequent submersion of the world in water. Afterward, the world will resurface anew and fertile, the surviving and returning gods will meet, and the world will be repopulated by two human survivors. Ragnarök is an important event in the Norse canon, and has been the subject of scholarly discourse and theory.

Ragnarök is the fifth album, released in 1995 on Metal Blade Records, by the rock/heavy metal/punk band Gwar. This album contains the most varied vocal stylings of any Gwar album, as the majority of the band lends their lungs to the tracklist (only We Kill Everything features as many different vocalists), as well as guest villain Cardinal Syn.
