The National Assembly (Khmer: រដ្ឋសភា, UNGEGN: Roatsaphea [rɔət.sapʰiə]; lit. 'State Assembly') is one of the two houses (chambers) of the Parliament of Cambodia. It is referred to as the lower house, with the Senate being referred to as the upper house.

The National Assembly is an elected body consisting of 125 members known as Members of Parliament (MPs). Members are elected for five-year terms by party-list proportional representation, using provinces as constituencies of 1 to 18 members, and the D'Hondt method of seat distribution. A political party must secure 63 seats to obtain and preserve a majority.

The National Assembly is headed by the President, currently Khuon Sodary. The seventh National Assembly held its inaugural session on 21 August 2023.

The current National Assembly originated as the Constituent Assembly, a legislative body elected during the United Nations Transitional Authority in Cambodia (UNTAC). After the 1993 election, the Assembly met and adopted a new constitution for Cambodia. After enactment of the 1993 Constitution, the Constituent Assembly was renamed the National Assembly.

The Constitution of Cambodia states the National Assembly are elected 5 year terms from 25 multi-member constituencies based on the provinces by closed list proportional representation. Seats were allocated using the D'Hondt method and elections are to happen on the fourth Sunday of July.

The qualifications to be a candidate for the National Assembly are outlined in Article 76 of the 1993 Constitution.
