2023 Mauritanian parliamentary election

The 157 members of the National Assembly are elected by two methods; 113 are elected from single- or multi-member constituencies using either the two-round system or proportional representation; in single-member constituencies candidates require a majority of the vote to be elected in the first round and a plurality in the second round. In two-seat constituencies, voters vote for a party list (which must contain one man and one woman); if no list receives more than 50% of the vote in the first round, a second round is held, with the winning party taking both seats. In constituencies with three or more seats, closed list proportional representation is used, with seats allocated using the largest remainder method.[2] For three-seat constituencies, party lists must include a female candidate in first or second on the list; for larger constituencies a zipper system is used, with alternate male and female candidates.[2]

The other 40 seats are elected from a single nationwide constituency, also using closed list proportional representation, with half elected on separate lists reserved for women.[2] A further four members are elected by the diaspora.
