The 17th Legislature of the Third Portuguese Republic () is the current meeting of the Assembly of the Republic. It first convened on 3 June 2025, with its membership being determined by the results of the 2025 Portuguese legislative election held the previous 18 May.
The 18th Portuguese legislative election was held on 18 May 2025. The Democratic Alliance (AD) was re-elected with a stronger mandate, albeit without a majority. For the first time in democracy, PS fell to third place, while Chega became the second-largest party in the Assembly.
The election of a new President of the Assembly of the Republic was held in the first session of the new Legislature, on 3 June 2025. Incumbent President José Pedro Aguiar-Branco, from the Social Democratic Party (PSD) was the sole candidate and was re-elected by a landslide.
The election of four new Vice Presidents of the Assembly of the Republic were held in the first session of the new Legislature. The name designated by Chega for second Vice President, incumbent Vice President Diogo Pacheco de Amorim, failed to be elected, which led to a vacancy in the seat.
A second ballot was held on 17 June 2025, with Diogo Pacheco de Amorim once again being a candidate. This time, he was elected with 145 votes in favour.
Gabriel Mithá Ribeiro resigned from Parliament on 22 September 2025, citing disagreements with the leadership of the party. On 26 September 2025, Chega proposed Francisco Gomes for Secretary, but he was rejected.
On 6 March 2026, Chega once again proposed a new name for the post, this time José de Carvalho. He ended up being elected.
Filipe Melo, the proposed name from Chega for Deputy Secretary, was rejected. As such, a second ballot was held on 17 June 2025, where he was elected.
