Hellbastard are a crust punk band, formed in 1984/5 in the United Kingdom. Members "Scruff Lewty" and "Scotty" met at a Subhumans gig and soon after formed Hellbastard, which was to be a combination of Crass-like politics and the music of Slayer. In 1990, after several EPs and full-lengths, the group appeared on the Combat-Earache compilation album, Grindcrusher, with the song "Justly Executed", from the Earache Records Natural Order LP.

They are considered to be a hugely influential band in the crust punk genre. The genre subsequently adopted its name from the band's first demo, Ripper Crust. They are also considered to be a part of the crossover thrash scene. One member of Hellbastard later went on to form Hellkrusher. At one time Vocalist/Guitarist "Scruff lewty" and ex-guitarist "Nick" played for their friends ' band "Energetic krusher". Hellbastard also passed on a deal with "Vinyl Solution" Records in 1989 and gave the chance to Energetic Krusher, subsequently their "Path To Oblivion" Album appeared soon after. Hellbastard opted to sign with Earache Records.
