Local elections were held on 13 May 2023 to elect the 21 members of the Municipal Council of Nouadhibou, as part of the 2023 Mauritanian local elections.
Mayor El Ghassem Ould Bellali was re-elected with a two-point increase on his party El Karama's vote share compared to the first round of the 2018 local election.
On 26 September 2022 all Mauritanian political parties reached an agreement sponsored by the Ministry of Interior and Decentralisation to reform the election system ahead of the upcoming elections after weeks of meetings between all parties.[1]
In this election, local councils will be elected in a single round using proportional representation through the largest remainder method, with no threshold being applied. The head of the list that gets the most votes will automatically become mayor of the city council.[1] [2]
