Joris Voorn (born 25 February 1977 in Moergestel) is a Dutch DJ who resides in Amsterdam. Joris is the co-owner of the Amsterdam based labels Rejected (with Edwin Oosterwal) and Green. He plays his own house-style which is considered close to Detroit Techno. Additionally Joris is a graduate in interior architecture.

Like many musicians, Voorn had a strong affiliation with music at a young age growing up in the city of Schiedam when he learned how to play the guitar and violin (his father was a composer of music). However, once the radio opened his mind to newer influences, Voorn became hooked on techno. During his education he won a DJ competition in Enschede which kick-started Joris' music career. Since 1997 Joris has been regularly booked for gigs and had a residency at the ATAK. However his first production was not until 2002 when he released his "Muted Trax" EP. This release, as well as support from Carl Craig, Derrick May and Laurent Garnier made him decide to (temporarily) give up interior architecture and focus on his DJing career. In 2003 his "Lost Memories" EP became another hit. In the same year Joris was crowned Talent of the Year at the Dutch DJ Awards.
