List of prime ministers of Elizabeth II

Since succeeding her father on 6 February 1952, Queen Elizabeth II has been head of state of 32 different independent states; currently, there are 16 states, called Commonwealth realms. Within the Westminster system in each realm, the Queen's government is headed by a prime minister. Appointment and dismissal of prime ministers are common reserve powers that can be exercised by the Queen or her governors-general.
This list does not cover Commonwealth nations that are not Commonwealth realms, nor holders of offices of prime minister in colonies or sub-national entities such as states or provinces.
The Queen has had over 170 individuals serve as her realms' prime ministers throughout her reign, the first new appointment being Dudley Senanayake as Prime Minister of Ceylon and the most recent being Johnny Briceño as Prime Minister of Belize; some of these individuals have served multiple non-consecutive terms in office (within the same state) as prime minister. Several of the Queen's prime ministers from various realms have been appointed for life to the Privy Council of the United Kingdom.
