Damage Done[4] is the sixth studio album by Swedish melodic death metal band Dark Tranquillity.

Here, the band returns to a more classic style while holding the changes made in their albums Haven and Projector, especially in the keyboards, but this is the first record since The Mind's I that does not feature clean vocals.

The song "Cathode Ray Sunshine" is featured in the video game's soundtrack, Brütal Legend.

Several versions of the album feature a bonus track entitled "I, Deception" as well as the "Monochromatic Stains" video clip but it is known that the limited edition digipak contains them.
