The Commonwealth secretary-general, formally the secretary-general of the Commonwealth of Nations, is the head of the Commonwealth Secretariat, the central body which has served the Commonwealth of Nations since its establishment in 1965, and responsible for representing the Commonwealth publicly. The Commonwealth secretary-general should not be confused with the head of the Commonwealth.
