Mark James (born October 16, 1961), better known by his stage name The 45 King, is an American DJ and record producer from the Bronx, New York. He started DJing in New Jersey during the mid-1980s. The nickname "the 45 King" came from his ability to make beats using 45 RPM records. He is best known for his breakbeat record "The 900 Number", producing the songs "Hard Knock Life (Ghetto Anthem)" for Jay-Z and "Stan" for Eminem, and for leading the Flavor Unit, which included members such as Queen Latifah, Apache, Chill Rob G and Lakim Shabazz.
