Constitutional Assembly elections were held in South Vietnam on 4 March 1956. A total of 431 candidates contested the 123 seats from all five registered pro-government political parties, with 11 elected as pro-government independents. Due to President Diem's policy of repression against the opposition and rigid control of the elections in order to prevent infiltration of Viet Cong communist elements, no opposition candidates were allowed to stand. Two deputies were not permitted to take seats due to electoral violations, making the total number of deputies seated at 121. On 26 October the body was transformed into the National Assembly after the new constitution came into effect.
