This article is about the US military rank. For the main character in Halo: Combat Evolved and Halo 2, see Master Chief (Halo).

Master Chief Petty Officer is the ninth, and highest, enlisted rank in the U.S. Navy, just above Senior Chief Petty Officer, and is a non-commissioned officer. They are referred to as Master Chief in most circumstances.

Advancement to Master Chief Petty Officer is similar to that of Chief Petty Officer and Senior Chief Petty Officer. It carries requirements of time in service, superior evaluation scores, specialty examinations, and peer review. A Senior Chief Petty Officer can only advance if the existing master chiefs approve.

A Master Chief Petty Officer is purely administrative and is usually tied closely with the Commanding Officer, except possibly when the command is very large (e.g. an aircraft carrier). Their uniform reflects this administrative duty; becoming similar to that of an officer, albeit with different insignia than an officer.

There exists one post, Master Chief Petty Officer of the Navy, which is unique. The holder of this post represents the most senior enlisted member in the U.S. Navy. The current incumbent is MCPON Terry D. Scott (SS/AW).
