General elections were held in the Democratic Republic of the Congo between 18 March and 30 April 1965, following the promulgation of a new constitution approved by a referendum the previous year.

223 political parties contested the election for 167 seats in the Chamber of Deputies.

The Léopoldville Court of Appeal accepted six of them, and re-runs were required in Kivu Central, Goma-Rutshuru, Cuvette Centrale, Fizi, Kwilu and Maniema, which were held between 8 and 22 August 1965.

[1] Despite Tshombe's party winning the election, President Joseph Kasa-Vubu appointed Évariste Kimba of the Congolese Democratic Front Prime Minister, a situation which ultimately led to Joseph Mobutu carrying out a military coup in November.

By the next election in 1970, Mobutu had eliminated all opposition parties, allowing his Popular Movement of the Revolution to run unopposed.
