Elections to the Territorial Assembly of the French colony Upper Volta are held. After the elections PDU and MDV form a government.

Territorial Assembly elections were held in French Upper Volta on 31 March 1957. The result was a victory for the Unified Democratic Party, which won 33 of the 68 seats in the Assembly.

Upper Volta was a colony of French West Africa established in 1919 in the territory occupied by present-day Burkina Faso. It was formed from territories that had been part of the colonies of Upper Senegal and Niger and the Côte d'Ivoire. The colony was dissolved on 5 September 1932, with parts being administered by the Côte d'Ivoire, French Sudan and the Colony of Niger.

Unified Democratic Party, was, despite its name, not a political party but an electoral alliance of two parties, the Voltaic Democratic Party (PDV-RDA) and the Social Party for the Emancipation of the African Masses (PSEMA), ahead of the 1957 territorial assembly elections in Upper Volta. PDU won 33 out of 70 seats.

The Voltaic Democratic Movement was a political party in Upper Volta, led by Gérard Kango Ouédraogo. MDV was founded in 1955.
