Opera Diabolicus is a Swedish horror-themed metal project established in Gothenburg in the mid-2000s by David Grimore and Adrian de Crow, drawing from epic heavy metal, gothic doom, and symphonic progressive metal in the tradition of King Diamond and Therion.

Their sound is ornate and deliberately cinematic, prioritizing atmosphere and narrative coherence over conventional metal structure.
