The Commander-in-Chief of the Armed Forces of Democratic People's Republic of Korea is the commander-in-chief of the Korean People's Army, the military of North Korea. The office was established on 4 July 1950 and abolished with the passing of a new constitution in 1972. Since then, the office of President of North Korea, the Chairman of the National Defence Commission and the President of the State Affairs Commission have been referred to as supreme commanders in accordance with the constitution.

The Korean People's Army encompasses the combined military forces of North Korea and the armed wing of the Workers' Party of Korea (WPK). The KPA consists of five branches: the Ground Force, the Naval Force, the Air Force, Strategic Force, and the Special Operation Force. It is commanded by the WPK Central Military Commission, which is chaired by the WPK general secretary, and the president of the State Affairs; both posts are currently headed by Kim Jong Un.
