Jørn Stubberud (born April 13, 1968) is a Norwegian musician. He is best known as the bassist in the black metal band Mayhem under the stage name Necrobutcher. He is one of the founding members of Mayhem along with Euronymous and Manheim.
He was in the band since 1983, but left in 1991 due to personal concerns over media and police attention following the suicide of former vocalist Dead. He was replaced by Varg Vikernes as a session bassist. He returned in 1995 and still plays in the band; however, according to Mayhem guitarist Blasphemer, he did not play bass on their most recent album Ordo Ad Chao. He has also played in other bands: L.E.G.O., Kvikksølvguttene, Bloodthorn and Checker Patrol.
He, along with Mayhem guitarist Blasphemer, is featured in the documentary Metal: A Headbanger's Journey, in which Stubberud gives a drunken and profane interview to Sam Dunn.
