Deadache is the fourth studio album by Finnish rock band Lordi, released in October 2008. For the release of the album the band renewed their monster outfits.

Deadache is a melodic hard rock album but has a heavier sound and includes more horror-themes than Lordi's previous albums. The album has more keyboard parts than The Arockalypse, and the song "The Rebirth Of The Countess", composed by the keyboard player Awa, includes a spoken part in French. "Missing Miss Charlene" includes singing by a children's choir, with the outro being already recorded in 1986 by a 12-year-old Mr. Lordi and some of his friends from his hometown of Rovaniemi. The organ in the intro and between the verses in the song "The Devil Hides Behind Her Smile" is taken from "The Phantom of the Opera".
