Immortal is a black metal band from Bergen, Norway, founded in 1990 by frontman and guitarist Abbath Doom Occulta (Olve Eikemo) and former guitarist Demonaz Doom Occulta (Harald Nævdal). The pair worked with various drummers (including Grim, Armagedda and Hellhammer) for their first three albums, and were later joined by current drummer Horgh (Reidar Horghagen) in 1996.

In March 2015, Abbath announced that the band split up and he will be forming a new band under his name, Abbath. However, in August 2015, Demonaz and Horgh claimed that the band "never stopped", and that it would continue without Abbath.
