The Master Chief Petty Officer of the Navy Badge is an identification badge of the United States Navy which is presented to the Master Chief of the Navy (MCPON) upon assuming office. The Master Chief Petty Officer of the Navy Badge is the highest in a series of Chief Petty Officer Identification Badges and is worn on the lower left pocket below all awards and warfare pins.

Since the Master Chief Petty Officer of the Navy badge is considered an identification pin, there are no additional criteria for its issuance other than the wearer hold the office of MCPON. It is typically not issued as an award on a DD Form 214 but, as the office of MCPON is normally a terminal assignment, the Master Chief Petty Officer of the Navy Badge is normally included as a decoration in retirement shadow boxs.
