Kotiteollisuus is a Finnish hard rock/metal band that was formed in 1991 in Lappeenranta, Finland. The band released its first demo tape in 1993 under the name "Hullu Ukko Ja Kotiteollisuus". The shortened name and current line-up (Jouni Hynynen, Jari Sinkkonen, Janne Hongisto) was established in 1997 when Aki Virtanen left the band.
Kotiteollisuus is said to combine "furious heavy metal with Finnish sullenness". Subjects frequently touched upon in songs are the current state of the nation, religion and mankind in general.
