Denaun Porter (born December 7, 1972 in Detroit, Michigan), known by his stage name Kon Artis, or production title Mr. Porter, is a rapper and producer, who rose to fame as an original member of Detroit rap collective D12.

Porter started his rap career at a young age, when his original dream of playing professional basketball in the NBA was shattered after receiving gun wounds to his leg. He founded the rap duo Da Brigade before being approached by late rapper Proof to start the hip hop group now known as D12. After Eminem rose to prominence, he signed Porter along with the rest of D12 to Shady Records. While on the label they have released two albums, with a third in production.

Alongside his rapping career, Porter also doubles as a successful hip hop music producer under the alias Mr. Porter. He has also dabbled in singing, performing the chorus of "Look At Me Now " from Young Buck's debut album Straight Outta Ca$hville, demonstrating a surprising vocal range. He has produced for the likes of Method Man, Snoop Dogg, Obie Trice, Eminem, Busta Rhymes and Young Buck. He created the beat heard in the highly successful single "P.I.M.P. ", for label-mate 50 Cent, and followed up with another smash hit "Stunt 101 " for the rap group G-Unit. He is currently doing production on Keyshia Cole's debut album Tears from a Soldier's Heart .
