美国空军参谋长（CSAF）是美国空军军阶最高的军官，是参谋长联席会议成员之一。空军参谋长领导空军参谋部，并受空军部长的直接领导负责空军全盘事务。在空军部长的授权下，参谋长负责在本土以及海外超过70万现役、国民警卫队、后备队、文职人员的组织、训练与装备保障。。空军参谋长还负责联合战斗司令部中空军人员的人事和资源调配。。空军参谋长还行使美国法典第10编第8033节赋予的其他职责、负责空军部长委派的其他任务，或将这些责任和义务进一步委派给其下属。

空军参谋长由总统提名，在参议院取得多数赞成即可就职。根据法令，空军参谋长由一名四星上将担任。与其他参谋长联席会议成员一样，空军参谋长为行政职务，并无对美国空军的作战指挥权。

The Chief of Staff of the Air Force (acronym: CSAF, or AF/CC) is a statutory office (10 U.S.C. § 8033) held by a four-star general in the United States Air Force, and is the most senior uniformed officer assigned to serve in the Department of the Air Force, and as such is the principal military advisor and a deputy to the Secretary of the Air Force; and is in a separate capacity a member of the Joint Chiefs of Staff, and thereby a military adviser to the National Security Council, the Secretary of Defense, and the President. The Chief of Staff is typically the highest-ranking officer on active-duty in the U.S. Air Force unless the Chairman and/or the Vice Chairman of the Joint Chiefs of Staff are Air Force officers.
