Chimera is the third full length album by the Norwegian black metal band Mayhem. It is the fourth and last main Mayhem release to feature vocalist Sven Erik Kristiansen (Maniac). TurboNatas of fellow Norwegian band Red Harvest provided the album artwork. The album art is a screenshot from the 1922 silent film Häxan.
At the time of its release in 2004, Mayhem was still being sharply and routinely criticized in the metal underground for straying from the black metal style on its foregoing album, Grand Declaration of War.
