Damnation is the seventh studio album by Swedish progressive metal band Opeth. It was released on 22 April 2003, five months after Deliverance, which was recorded at the same time. Damnation is the last Opeth album to date to be produced by Steven Wilson although he did mix two future albums, Heritage and Pale Communion. Mikael Åkerfeldt dedicated both Damnation and Deliverance to his grandmother, who died in a car accident during the time the albums were being recorded.

Progressive metal is a broad fusion music genre melding heavy metal and progressive rock, combining the loud "aggression" and amplified guitar-driven sound of the former with the more experimental, cerebral or quasi-classical compositions of the latter.
