Jens Christian Bugge Wesseltoft (born 1 February 1964 in Porsgrunn) is a Norwegian jazz musician, pianist, composer and producer. He has his own label named Jazzland Records. In the 1990s, Bugge has made a transition from Nordic jazz traditions exemplified by the ECM record label to a style sometimes referred to as "future jazz" or nu jazz. He has played with Jan Garbarek.
He also received in 1996 the Spellemannprisen for his album New Conception of Jazz, also in 1998 and 2002 for his albums with Sidsel Endresen, Duplex Ride and Out Here, In There.
The track "Existence" could be heard in Philippe Harel's movie "Extension du domaine de la lutte", adaptation of Michel Houellebecq's roman, written in 1994.
