Duwaine Whitfield, better known by the stage name Wittyboy, is a British DJ, record producer and remixer from Leeds, West Yorkshire, England.

Whitfield was raised in Leeds where he was influenced by a mix of speed garage, grime, hip hop, house and dancehall from an early age.

He began to gain support on national radio stations along with regular nightclub performances within the bassline scene.

After a number of successful underground releases, Wittyboy was given his first major label opportunity, remixing singer Estelle's "No Substitute Love" (Atlantic Records).

Wittyboy has been featured on a number of compilations such as Nitin Sawhney's London Undersound and Instrumentals, Pure Garage Rewind: Back to the Old Skool and Pure Bassline, both mixed by DJ EZ (Warner Music UK), Ministry of Sound's The Sound of Bassline series and Fabric Live 47.
