Jussi Chydenius (born 30 December 1972) is a Finnish musician and composer.
He played drums for the rock band Don Huonot from 1989 to 2001 and was a founding member.
Chydenius was elected at the City Council of Helsinki in 2001 where he is also a member of the Cultural Board.
In a review of a recent Rajaton concert, one writer noted that Chydenius, "sounds like a double-bass or creates an entire drum corps, realistically snapping out a snare drum rhythm and rolling it off into silence."
The tiniest vocal inflection is inserted precisely in place, not studied, but spontaneous.
