This is a list of the heads of state of Nigeria, from the independence of Federation of Nigeria in 1960 to the present day.
From 1960 to 1963 the head of state under the Nigeria Independence Act 1960 was the Queen of Nigeria, Elizabeth II, who was also monarch of the United Kingdom and the other Commonwealth realms. The Queen was represented in Nigeria by a Governor-General. Nigeria became a republic under the Constitution of 1963 and the monarch and Governor-General were replaced by a ceremonial President. In 1979, under the 1979 Constitution, the President gained executive powers, becoming head of both state and government. Since 1994, under the 1993 Constitution and the current 1999 Constitution, the head of state and government has been called the President.
The succession to the throne was the same as the succession to the British throne.
The Governor-General was the representative of the monarch in Nigeria and exercised most of the powers of the monarch. The Governor-General was appointed for an indefinite term, serving at the pleasure of the monarch. After the passage of the Statute of Westminster 1931, the Governor-General was appointed solely on the advice of the Nigerian cabinet without the involvement of the British government. In the event of a vacancy the Chief Justice would have served as Officer Administering the Government.
Under the 1963 Constitution, the first constitution of the Republic of Nigeria, the President replaced the monarch as ceremonial head of state. The President was elected by Parliament for a five-year term. In the event of a vacancy the President of the Senate would have served as Acting President.
