This article only lists elections held after the introduction of multi-party politics with the 1991 Constitution, introduced after a referendum.
During the authoritarian regime of Ould Daddah elections that were not up to democratic standards were held under a one-party state, while elections weren't held during a period of military junta rule after Mauritania's participation in the Western Sahara War.
The latest election was held on 22 June 2019, marking Mauritania's first peaceful transfer of power in the presidency.
Mohamed Ould Ghazouani (UPR) won the election in the first round, securing 52% of votes.
Mauritania's Parliament was bi-cameral between 1991 and 2017, with an indirectly elected upper house (the Senate) being abolished after a 2017 constitutional reform approved through a referendum.
