Sanullim (산울림, 1971~2008), also spelled Sanulrim, is a South Korean power trio rock band. The name of the band is the combination of words, "san" (산, mountain) and "ullim" (울림, echo). The band is considered to be one of the most influential figures in Korean rock music. Their musical experiments varied from songs for children to progressive/psychedelic rock.
Sanullim broke up after the death of the drummer, Kim Chang-ik (김창익), in 2008.
