Lärm (German for noise) were a Dutch straight edge thrashcore band formed in 1981, first playing under the name of Total Chaoz. Lärm pioneered what would later be called power violence, along with bands Heresy and Siege. However, they referred to their music as "extreme noise", though having nothing to do with noise rock or noise music.

Due to members being straight edge, which was something uncommon in the crust punk scene, Lärm were different from many bands at the time. The group also turned down contracts from record labels like Nuclear Blast, eventually resulting in their break up. Members went on to form Seein Red and the communist straight edge band Manliftingbanner, who played in a more conventional Hardcore Punk style.

Since 2003, Lärm played one show a year, though most have been with stand-in vocalists. Seein' Red has re-recorded some Lärm songs under the name Lärm as Fuck. They played their final show to date in 2012.
