Sanullim (산울림, 1977~2008), also spelled as Sanulrim, is a South Korean power trio rock band. The name of the band is the combination of words,'san'(산, mountain) + 'ullim'(울림, echo). The three members of Sanullim are brothers. Kim Chang-wan(김창완, vo. gt., 1954~), Kim Chang-hoon(김창훈, bs., gt., 1956~), Kim Chang-ik(김창익, ds.1958~2008).The band released their first album in December 1977. The album much impact to the Korean music secene and became a great hit. The band is considered as one of the most influential figures in the Korean Rock scene. The musical experiments they tried vary from songs for children to progressive/psychedelic rock. Sanullim broke up after the death of the drummer, Kim Chang-ik(김창익), in 2008.

The music they played in their first album was something the people had never heard before. The people were absorbed with the psychedelic/hard rock sound the band produced. The great impact they brought resembled that of Sex Pistols which also made their debut in 1977. Sanullim's appearance in the music secene was also dramatic and significant because they vitalized the Korean music scene which was much devastated after several major musicians were arrested for having marijuana around the middle of 1970's.
