Associação Portuguesa de Desportos, commonly referred to as Portuguesa or Lusa, is a Brazilian professional football club based in the district of Pari, São Paulo, that competes in the Campeonato Paulista, the top tier of the São Paulo state football league, and the Campeonato Brasileiro Série D. It is part of a sports club, founded on 14 August 1920, by the Portuguese population of the city.

In 1956, Portuguesa bought from São Paulo a big piece of land located in the limits between the northeast and center of the city.

The chairman disappointment with the awful campaign in a much considered easy tournament led to the dismissal of the team's coach, Jorginho, after 14 months working for the Lusa side.

Lusa started the Campeonato Brasileiro Série A with their goalkeeper Wéverton negotiating with his departure to play for Atlético Paranaense.

[12] Despite having Brazilian international and former Ballon d'Or winner Ronaldinho, the Atlético side struggled to get out of the strong midfield pressure and ball possession imposed by Lusa, which had played the majority of the second half with a one-man advantage after defender Leonardo Silva was sent off.

[20] On 10 January 2014, a supporter from the club won a lawsuit in São Paulo's courts, which determines the points would be returned to Portuguesa, relegating Flamengo.

Argel left Lusa in the following month, and after short-reign terms of Marcelo Veiga and Silas, the club announced the arrival of Vágner Benazzi in mid-September, highly known for his abilities to guide a team out of the relegation places.

On 20 March, after being highly pressured, president Ilídio Lico resigned and was replaced by Jorge Manuel Marques Gonçalves.

During the year's Série C, Portuguesa qualified to the final rounds as second in its group, but missed out promotion after losing to eventual champions Vila Nova.

Portuguesa suffered another relegation in the end of the 2016 season, after a 0–2 away loss against Tombense, being demoted to Série D ahead of the 2017 campaign.

Ahead of the 2017 season, Portuguesa announced Émerson Leão as their football consultant, with Tuca Guimarães being appointed as head coach.

During the 2018 campaign, Lusa had Guilherme Alves and Allan Aal as their head coaches, finishing in both disappointing mid-table positions in the Série A2 and in the Copa Paulista.

In the 2019 season, the first team was managed by Luís Carlos Martins, Vica and former youth graduate Zé Maria, again with little success.

[23] The club started the 2023 season with Mazola Júnior as head coach, and narrowly avoided relegation in the 2023 Campeonato Paulista under Gilson Kleina, who opted to leave the club at the end of the competition; in that year, they also introduced a new Rooster of Barcelos-themed third kit, which was inspired on a popular Portuguese folk tale and symbol.

On 7 November 2024, an offer from a group of investors (Tauá Partners, Revee and XP Investimentos) was presented to Portuguesa's Council to purchase 80% of the club's Sociedade Anônima do Futebol project, which included an investment of R$ 1 billion to clear the club's debt and build a new arena in the place of the current Estádio do Canindé.

The Cross of Avis represents Portuguese independence from the Kingdom of Castille, which happened after the Battle of Aljubarrota on 14 August 1385.

Portuguesa's first kit, introduced on 20 September 1920, was an all-red shirt, white shorts, and red socks with two horizontal green lines.
