The XXIII Constitutional Government of Portugal (Portuguese: XXIII Governo Constitucional de Portugal) was the 23rd government of the Third Portuguese Republic under the current Constitution, and had António Costa as the Prime Minister, in his third consecutive term.

It was in office from 30 March 2022 to 2 April 2024 and was formed by members of the Socialist Party (PS).

[5] Costa met with the President of Portugal Marcelo Rebelo de Sousa and announced his resignation in a televised statement in the afternoon, saying that "the dignity of the functions of prime minister is not compatible with any suspicion about his integrity, his good conduct and even less with the suspicion of the practice of any criminal act".

[6] On 9 November 2023, after meeting with the Council of State and talking with the political parties represented in the parliament, president Rebelo de Sousa announced snap legislative elections to be held on 10 March 2024.

[7][8] On 2 April 2024, the new center-right minority government, led by Prime Minister Luís Montenegro, took office to succeed António Costa, resulting from the slim victory of the Democratic Alliance in the snap election.
