General elections were held in Haiti on 22 September 1957. Former Minister of Labour François Duvalier won the presidential election running under the National Unity Party banner, defeating the wealthy mulatto Louis Déjoie, as well as independent moderate Clement Jumelle, who had dropped out on election day in a cloud of suspicions that the army was monitoring the election in favour of Duvalier. Former head of state Daniel Fignolé, considered a champion of poor blacks, was considered ineligible as he had been forcibly exiled months before the election, allegedly kidnapped.
Supporters of Duvalier also won the Chamber of Deputies elections. Following the election, Déjoie went into exile in Cuba along with his supporters, fearing repression from Duvalier supporters. Haiti was not to see a free or semi-free election until after the fall of Duvalier's son Jean-Claude Duvalier in February 1986.
