Mustafa Fevzi Çakmak was a Turkish field marshal (Mareşal) and politician. He served as the Chief of General Staff from 1918 and 1919 and later the Minister of War of the Ottoman Empire in 1920. He later joined the provisional Government of the Grand National Assembly and became the Deputy Prime Minister, Minister of National Defense and later as the Prime Minister of Turkey from 1921 to 1922. He was the second Chief of the General Staff of the provisional Ankara Government and the first Chief of the General Staff of the Republic of Turkey.

Field marshal is the second most senior military rank, ordinarily senior to the general officer ranks, but junior to the rank of Generalissimo. Usually, it is the highest rank in an army, and as such, few persons are ever appointed to it. It is considered as a five-star rank (OF-10) in modern-day armed forces in many countries. Promotion to the rank of field marshal in many countries historically required extraordinary military achievement by a general. However, the rank has also been used as a divisional command rank and also as a brigade command rank. Examples of the different uses of the rank include Afghanistan, Austria-Hungary, Pakistan, Prussia/Germany, India and Sri Lanka for an extraordinary achievement; Spain and Mexico for a divisional command ; and France, Portugal and Brazil for a brigade command.
