A defensive coordinator is a member of the coaching staff of a gridiron football team who is in charge of the defense.
 Generally, along with the offensive coordinator, he represents the second level of command structure after the head coach.
 The defensive coordinator is generally in charge of managing all defensive players and assistant coaches, of developing a general defensive game plan, and of calling the plays for the defense during the game.
 At higher levels of football (college and professional), the defensive coordinator typically has a number of assistant coaches working under him who are responsible for the various defensive positions on the team (such as defensive line, linebackers, or defensive backs).
