# 2018 Mauritanian regional elections

Regional elections were held in Mauritania on 1 and 15 September 2018, alongside parliamentary and local elections. They were the first elections to the newly created regional councils.

## Background

Regional councils were created in Mauritania following a 2017 constitutional referendum that abolished the Senate, replacing it with regional councils in every wilaya and a single one for the city of Nouakchott.

## Election system

Regional councils in Mauritania are elected using the proportional representation system of the largest remainder method with two rounds. In the first round, voters choose from one of several lists running. If one list obtains an absolute majority of votes, the council seats would be then distributed proportionally. If not, a second round must be held between the two largest lists. The president of the Regional Council is elected by the Regional Council from one of their members.

## Regional governments

The following table lists party control in each regional council after the election.
