Parliamentary elections were held in South Vietnam on 27 September 1963. All but 3 of the 123 seats in the National Assembly were won by President Diem's regime. Three seats were won by the opposition Social Democratic and Dai Viet parties. As this election took place during the Buddhist crisis of 1963, the government allowed elements of the opposition to stand during the elections as one of the concessions to Buddhist protest leaders. However, due to the 1963 South Vietnamese coup, the National Assembly was not able to convene its first inaugural session and was forced to dissolve by the military.
