Chief Master Sergeant (CMSgt) is the ninth, and highest, enlisted rank in the U.S. Air Force, just above Senior Master Sergeant, and is a senior non-commissioned officer rank. The official term is "Chief Master Sergeant" or "Chief".

Attaining the rank of Chief Master Sergeant is the pinnacle of an Air Force enlisted person's career. Some Chief Master Sergeants manage the efforts of all enlisted personnel within their unit or major subsection while others run major staff functions at higher headquarters levels. All Chief Master Sergeants are expected to serve as mentors for non-commissioned officers and junior enlisted members, and to serve as advisers to unit commanders and senior officers.

By federal law, roughly one percent of the Air Force enlisted force may hold the rank of chief master sergeant.
