Jouni Kalervo Hynynen (born February 15, 1970, in Joutseno, Finland) is the guitarist/vocalist in Kotiteollisuus, a Finnishheavy metalband. He also writes the band's music along with his bandmates, and contributes majority of the lyrics. He has also written books, hosted a reality TV show called "Äijät" ('The men') with Jone Nikula and been a columnist for newspapers. He is known not only for his desperate and dark lyrics and his extraordinary looks and attitude, but also his sense of humour, which can be seen, for example, in NO SORI!, where Hynynen is the "special editor-in-chief". Hynynen, alongside with his Kotiteollisuus bandmates Hongisto and Sinkkonen, and Antti "Hyrde" Hyyrynen of Stam1na, his brother Janne (ex-Mokoma) and Kaarle of Viikate use the magazine to make fun of tabloids, among other things.
