The following tables will show detailed results in all of the electoral districts of the country.

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] The 176 members (an increase of 17 members compared to 2018) of the National Assembly will be elected by two methods (with Mauritanians being able to cast four different votes in a parallel voting system); 125 are elected from single- or multi-member electoral districts based on the departments (or moughataas) that the country is subdivided in[a] (with the exception of Nouakchott, which has been divided in three 7-seat constituencies for this election based on the three regions (or wilayas) the city is subdivided in instead of the single 18-seat constituency that was used in 2018),[1] 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.

[3] 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.
