General elections were held in the Dominican Republic on 1 June 1966. Following the 1963 coup which toppled elected president Juan Bosch of the Dominican Revolutionary Party, supporters of his constitutional reforms were excluded from the elections, although Bosch himself contested them. The result was a victory for JoaquÃÂn Balaguer of the Reformist Party, whilst his party also won the Congressional elections. Voter turnout was 76%.
