Ninjaman, alias Don Gorgon, (born Desmond John Ballentine on January 20, 1966, in Annotto Bay, Jamaica) is a popular dancehall deejay, known for his controversial and pro-gun lyrics and his stuttering and melodramatic style. Ninjaman is currently in jail awaiting trial for a murder that was commited in Kingston, Jamaica.

After moving from his birthplace Annotto Bay to Kingston at the age of 11, he launched his deejay career with the Black Culture Sound System at age 12 as "Double Ugly". In 1980, he joined Killamanjaro, there got the chance to learn from established deejays Super Cat and Early B, and released his debut single as "Uglyman". Yet another name change made him the now well known Ninjaman. In 1987, Ninjaman recorded - and produced himself - his first hit single "Protection", a duet with Courtney Melody. The following years brought many prolific collaborations with producers like King Jammy, Witty, Xterminator, Philip "Fatis" Burrell, Redman, Ini Kamoze, Bobby Digital, Augustus "Gussie" Clarke, and Steely & Clevie and Henry "Junjo" Lawes. It has been said that Ninjaman comes up with all of his lyrics on the spot in the recording studio, in a freestyle manner.
