Unified Democratic Party (French: Parti Démocratique Unifié), 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.
After the elections PDU formed a government together with the Voltaic Democratic Movement (MDV).
PDU held seven ministries and MDV five.
PSEMA and MDV revolted against the vice-president Ouezzine Coulibaly and formed an opposition bloc, Voltaic Solidarity.
