Absurd is a German black metal band that has been classified as a "right-wing extremist" group by the Thuringian Landesbehörde für Verfassungsschutz.

The band was founded in Sondershausen by Hendrik Möbus (also known as Randall Flagg, Jarl Flagg Nidhögg and JFN) and Sebastian Schauseil (Dark Mark Doom) in 1992, with a third member, Andreas Kirchner, joining at a later stage.

Their lyrics concern nationalistic, pagan (Hendrik Möbus is the founder of the Deutsche Heidnische Front), pro-heathen revivalist Germanic, and anti-Judeo-Christian themes.

The band achieved infamy because its original members (not in the band since 1999) murdered Sandro Beyer, a 15-year-old boy, in 1993. The canonical motive is that Beyer was privy to an illicit relationship of Schauseil's with a married woman, and had been spreading rumours about this and other activities of the band. On 29 April in Sondershausen, the then-17-year-old band members Möbus, Schauseil, and Kirchner enticed Beyer to a meeting, and strangled him there with an electrical cord. Kirchner, in a now infamous quotation, was reported as saying: "Oh shit—now I've completely ruined my life." Schauseil claimed to have heard a voice in his head saying the nonsensical phrase "Kuster Maier", which he interpreted as "Töte Beyer" ("Kill Beyer").
