The Supreme Military Council was the body that ruled Nigeria after the 1966 coup d'état until it was dissolved following the 1979 parliamentary election and the Second Nigerian Republic.
According to a Constitutional Decree, published in Lagos on 17 March 1967, legislative and executive power was vested in the Supreme Military Council.
The initial President of the Supreme Military Council was Maj.-Gen. Yakubu Gowon, Commander-in-Chief of the Nigerian Armed Forces.
He was replaced by Murtala Muhammed (in 1975) and Olusegun Obasanjo (in 1976) in successive coups.
The Military Governors of the twelve states of the federation were ex-officio members of the committee.
