Elections in Mauritania

Elections in Mauritania encompass four different types: presidential elections, parliamentary elections, regional elections and local elections.

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.

Mauritania has a presidential election every five years, in which a President of Mauritania is elected in two rounds on the basis of a direct popular vote.

Parliamentary elections for the National Assembly are held every five years with a parallel voting system combining several national lists and an electoral district vote, with a two-round system used for one-seat districts, a general ticket used for two-seat districts, with larger districts using the proportional largest remainder method. Mauritania has a multi-party system with a dominant ruling party holding an absolute majority supported by several minor parties (with this bloc being referred to as the "presidential majority"). Mauritania has a high number of parties, with a peak of 105 parties running in 2018.

Regional and local elections are also held every five years (usually at the same time as parliamentary elections) to elect Mauritania's regional and local councils using a proportional largest remainder method. The presidency of said councils is held by the leader of the largest list in the election.
