The National Assembly (French: Assemblée nationale, Haitian Creole: Asanble Nasyonal) consists of the bicameral legislature of the Republic of Haiti, consisting of the upper house as the Senate (Sénat) and the lower house as the Chamber of Deputies (Chambre des Députés).

Following his 1806 assassination, his northern general and the new Chief of the Provisional Government Henri Christophe called a Constituent Assembly to meet in Port-au-Prince in November.

Petion eventually tired of the 1806 constitution's limitations on his power, and he eventually drafted a major revision to the constitution in 1816, which established a bicameral parliament, consisting of the House of Representatives of the Communes and the Senate, as well as a separate judicial branch headed by the Tribunal of Cassation.

But under his successor, Philippe Guerrier, the Parliament was temporarily replaced by a smaller appointed Council of State which held legislative power for the next two years until it was turned into a Senate in 1846 under Jean-Baptiste Riché.

After the elections of 2000, twenty-six of the then twenty-seven seats were held by Jean-Bertrand Aristide's Fanmi Lavalas party.

Following the coup d'état and the overthrow of the government in February 2004, the Chamber of Deputies remained empty.

The Legislative Palace (French: Palais Législatif)[2][3] was among the many structures which were virtually destroyed by the earthquake on 12 January 2010.

The second building, a tower of 9 levels, is going to be equipped with 4 main elevators, a freight elevator and emergency staircase, and will host the individual offices of senators and deputies, including their secretariats, waiting rooms, meeting rooms, space for clerks, toilets, kitchens and a parking of several levels with a capacity of 240 vehicles.
