Member State of the Arab League Regional elections were held on 1 September 2018, with a second round on 15 September 2018, to elect the 37 members of the newly-formed Regional Council of Nouakchott, created after the 2017 Mauritanian constitutional referendum in replacement of the Senate and the Urban Community of Nouakchott.

Ex-mayor of Tevragh-Zeina Fatimetou Mint Abdel Malick, running for the ruling party Union for the Republic won a narrow majority on the second round against Mohamed Jamil Ould Mansour, the opposition-backed candidate and previous leader of the Islamist Tewassoul party.

Mint Abdel Malick was first presented as candidate of the Union for the Republic on 8 July 2018 together with the rest of candidates to head the regional councils of the country.
