This is the results breakdown of the Assembly of the Republic election held in Portugal on 30 January 2022. The following tables show detailed results in each of the country's 22 electoral constituencies.

Controversies and accusations following the counting of overseas ballots, the Constitutional Court forced the repetition of the election in the Europe constituency, which elected two MPs.[1] The rerun of the election in the overseas constituency of Europe occurred, for in person voting, on 12 and 13 March 2022, and postal ballots were received until 23 March 2022.[2] The final, certified election results were published in the official journal, Diário da República, on 26 March 2022.[3]

Electoral system

The Assembly of the Republic has 230 members elected to four-year terms. The number of seats to be elected by each district depends on the district magnitude.[4] 226 seats are allocated proportionally by the number of registered voters in the 18 Districts in Mainland Portugal, plus Azores and Madeira, and 4 fixed seats are allocated for overseas voters, 2 seats for voters in Europe and another 2 seats for voters Outside Europe.[5] The 230 members of Parliament are elected using the D'Hondt method and by a closed list proportional representation system. Members represent the country as a whole and not the constituencies in which they were elected.[6]
