Américo Manuel Alves Aguiar (born 12 December 1973) is a Portuguese prelate of the Catholic Church who has been bishop of Setúbal since 2023.

[citation needed] He was president of the administrative board of Rádio Renascença (Lisbon) from 2017 while continuing to provide pastoral services in Porto.

[2] He received his episcopal ordination from the Cardinal Patriarch of Lisbon, Manuel Clemente, at the Santissima Trindade Church in Porto on 31 March 2019.

[6] He led the Commission for the Protection of Minors and Vulnerable Persons of the Patriarchate of Lisbon until March 2023, when the Portuguese Episcopal Conference decided that only laypeople should serve on such bodies.

[10][11] That this results in two active cardinals from the see of Lisbon has been called "a genuine novelty"[12] and provoked speculation about his future in the Roman Curia.

[17] In July 2023, being responsible for World Youth Day 2023, he declared in an interview that the purpose of the event was not "to convert young people to Christ".
