Obsessed by Cruelty is the 1986 debut album by the German thrash metal band Sodom. It was re-released together with In the Sign of Evil in 1988, and as picture vinyl in 2005 by Vinyl Maniacs/EMRmusic.

Though generally unknown, two different versions of this album exist. They had to record the album twice because their record company was not satisfied with the result. The first version was recorded in Berlin and the second version in Nuremberg. According to Tom Angelripper, the second recording is "completely different" and includes a bonus track called "After the Deluge" because they had a different guitar player.

Mayhem's founder guitarist Euronymous described this album (as well as Destruction's Sentence of Death) as an underrated "Masterpiece of Black Stinking Metal". He also named his record label, Deathlike Silence Productions, after the opening track of the album.
