"Armageddon It" is a song by the English rock band Def Leppard from their 1987 album Hysteria.

"Armageddon It" was one of the songs dating back to the initial writing sessions for Hysteria in Dublin in 1984.

On 12–13 February 1988, the band recorded two shows at the McNichols Arena in Denver, Colorado for a future live film release.

However, a month later, "Armageddon It" was set to be released as the sixth single off the popular Hysteria album and a promo video clip was urgently needed.

Although they were happy with the results for "Hysteria" and "Animal", they were very unsatisfied with the way "Pour Some Sugar on Me" had turned out for its concept.
