List of Prime Ministers of Cambodia

The Prime Minister of Cambodia is the Head of Government of the Kingdom of Cambodia. The Prime Minister is also the chairman of the Cabinet of Cambodia and represents the government at home and the country abroad. The Prime Minister is elected to a five-year term, with no term limits. Since 1945, there have been 36 prime ministers.

Constitutionally the Prime Minister is required to be a member of the Parliament. He must also gain their approval through a resolution before an official appointment by the King can take place. The traditional swearing-in ceremony takes place at the royal palace where the Prime Minister-elect has to take an oath of office in front of the King and the two Patriarch monks.

Incumbent Hun Sen has held the position since 14 January 1985 ().
