Joseph Hahn (born in Glendale, California March 15, 1977) is the Korean American DJ for nu metal band Linkin Park. Hahn attended Pasadena Art College of Design with fellow Linkin Park emcee Mike Shinoda, but didn't graduate from there.

Hahn's equipment includes the following:

• Vestax PDX-2000 Turntables
• Rane TTM 54 DJ mixer
• AKAI MPC 2000
• Emagic Logic Audio
• Various Effects
• Shure M44-7 needles
• Custom-made vinyl

For a time, there was a rumor that Hahn had a split personality called Remy. However, this was an in-joke from the band that was placed on Hahn's bio on a popular fansite. The webmistress of the site assumed that most readers knew it was only a joke; however some people didn't and the rumor still remains today.
