Dijon Isaiah McFarlane (born June 5, 1990), professionally known as Mustard (formerly DJ Mustard), is an American rapper, record producer, and DJ from Los Angeles, California.

While on an episode of Complex’s Everyday Struggle, Mustard revealed that he started as a DJ around the age of 12, however rather than by choice it was because he “was left out of parties, and it was [his] family’s business” and that his “uncle was a big DJ out here and [him] how to DJ.” Eventually, he moved on to DJ'ing his own parties at high school pep rallies, football games, and basketball games.
