Presidential elections were held in Mauritania on 7 August 1966. Following the merger of all the country's political parties into the Mauritanian People's Party (PPM), the country had become a one-party state in December 1961. Its leader, incumbent President Moktar Ould Daddah, was the only candidate, and was re-elected unopposed. Voter turnout was 96.2%.
