Marcos Aoás Corrêa (born 14 May 1994), better known as Marquinhos (), is a Brazilian professional footballer who plays as a centre-back for and captains both club Paris Saint-Germain and the Brazil national team.

Marquinhos began his career at Corinthians, and after winning the 2012 Copa Libertadores he moved to Roma for an eventual fee of €3 million. He was a regular in his only season as Roma reached the Coppa Italia final. In July 2013, he moved to PSG for €31.4 million, one of the highest fees for a player under the age of 20. Marquinhos played less frequently after the acquisition of compatriot David Luiz in 2014, returning to an integral role after the latter was sold in 2016. He was part of PSG's team that reached the 2020 UEFA Champions League final. After Thiago Silva's departure in August 2020, he took up the role of captain. He captained PSG to their first UEFA Champions League titles back-to-back in 2025 and 2026, with the former being part of a continental treble. In total with PSG, Marquinhos has won a record 11 Ligue 1 titles, 14 domestic cups, and two Champions League titles. He ranks top for all-time appearances for the club, with over 500.

Marquinhos made his full international debut for Brazil in 2013, and was part of their under-21 side which won the 2014 Toulon Tournament. He also represented the nation at the 2015 Copa América and the following year's Copa América Centenario, and won a gold medal at the 2016 Olympics. He subsequently took part in three FIFA World Cups (2018, 2022, and 2026) and three additional Copas América (2019, 2021, and 2024), winning the 2019 title.

Club career Corinthians Marquinhos joined Corinthians at the age of eight in 2002. After winning the state junior cup, he was first included in a senior matchday squad on 29 January 2012, remaining an unused substitute in their 1–0 home win over Linense in the Campeonato Paulista. He made his professional debut in the competition on 18 February, playing the full 90 minutes of a victory by the same score at São Caetano. He made eight appearances across the season, as the Timão topped the table in the regular season but were defeated by Ponte Preta in the play-offs quarter-finals.

After the conclusion of the state championship, Marquinhos made his Campeonato Brasileiro Série A debut on 20 May 2012, playing the full 90 minutes in a 0–1 loss to Fluminense at the Paulo Machado de Carvalho Stadium; both teams were resting players in the first game of the season due to concentration on the Copa Libertadores. He played six games in the national championship, and was an unused substitute as the club won the 2012 Copa Libertadores Finals against Boca Juniors.

Roma In July 2012, Marquinhos was signed by Italian club Roma from Corinthians. The transfer was initially a one-year loan for a fee of €1.5 million, rising to €3 million after he made eight first-team appearances of at least 45 minutes each. At Roma, he played under the name "Marcos" printed on his jersey to avoid confusion with teammate Marquinho.

Marquinhos made his debut on 16 September in a 2–3 loss against Bologna at the Stadio Olimpico, sent on by manager Zdeněk Zeman to replace Iván Piris for the match's final 15 minutes. By October, Zeman decided to partner Marquinhos for his speed alongside former Corinthians teammate and fellow Brazilian Leandro Castán in central defence, demoting former starter Nicolás Burdisso to the substitutes' bench. He given a straight red card in a 4–2 victory over Milan on 22 December when he was judged to have denied Stephan El Shaarawy a clear goalscoring opportunity.

Marquinhos played 26 Serie A games in his only season, and four in the Coppa Italia. This included the full 90 minutes of the final on 26 May, playing at right back as Roma lost 0–1 to Rome rivals Lazio.

Paris Saint-Germain 2013–2016: First seasons and starting XI competition On 19 July 2013, Marquinhos signed a five-year deal with French side Paris Saint-Germain for a fee of €31.45 million. According to BBC Sport, this was then the highest transfer fee for a teenager, although Sky Sports report it as then the fifth-highest such transfer, and France's Le 10 Sport record it as the third-highest. French news channel BFM TV described the transfer as the fifth most expensive of all time for a defender, after those of Rio Ferdinand, Thiago Silva, Lilian Thuram and Dani Alves. Marquinhos' transfer was threatened by anomalies in his medical exam, and he missed the team's pre-season visit to Sweden. His mother said that he had caught a virus, with PSG denying claims circulated by Le Parisien that he had hepatitis.

On his official debut for the club on 17 September, Marquinhos scored his first professional goal to confirm a 4–1 win against Olympiacos at the Karaiskakis Stadium in the group stage of the 2013–14 UEFA Champions League. Five days later, Marquinhos made his Ligue 1 debut as a starter in a 1–1 draw against Monaco. His first league goal for the club came on 28 September, the first in a 2–0 win over Toulouse. On 2 October, he scored the second goal in a 3–0 Champions League group victory against Benfica. Marquinhos, who was playing due to injury to Thiago Silva, expressed surprise at his goalscoring form at the start of his PSG career. Marquinhos scored the last goal of PSG's 6–1 aggregate win over Bayer Leverkusen in the last 16 of the Champions League on 12 March 2014, and was an unused substitute as they won the Coupe de la Ligue final against Lyon on 19 April. On 10 May, he scored the opening goal of a 3–1 win over Lille, which put by-then league champions PSG to a record league points tally of 86 with a game left to play.

Marquinhos began the 2014–15 season on 2 August in the Trophée des Champions, playing the whole 90 minutes as PSG won 2–0 against Guingamp at the Workers Stadium in Beijing. In the 32nd minute, he gave away a penalty kick by fouling Claudio Beauvue, but Salvatore Sirigu saved the penalty shot from Mustapha Yatabaré. His first goal of the season came in a 2–0 win at Caen on 24 September, heading in Javier Pastore's corner. On 26 March 2015, Marquinhos signed a one-year contract extension to keep him at the team until 2019. Club president Nasser Al-Khelaifi said that, "The biggest European clubs were interested in signing Marquinhos, so this contract extension further reinforces Paris Saint-Germain's ambitious long-term project." As the right-back in an all-Brazilian defence (alongside Maxwell, Thiago Silva and David Luiz), Marquinhos featured in PSG's 3–2 win at Marseille in Le Classique, scoring the equaliser. Six days later, he started in the 4–0 victory over Bastia in the 2015 Coupe de la Ligue, his 34th consecutive game without a defeat for the club, surpassing a record set by George Weah. On 16 May, PSG won their third consecutive league title with a 2–1 victory at Montpellier, with Marquinhos playing the final 12 minutes in place of Yohan Cabaye. Two weeks later, he was an unused substitute as the team finished a perfect domestic season with victory in the Coupe de France final against Auxerre.

PSG began the 2015–16 season with a 2–0 victory over Lyon in the 2015 Trophée des Champions, with Marquinhos an unused substitute as Serge Aurier played at right back. At the end of the summer transfer window, Chelsea had two bids rejected for his signature, of amounts between £25.7–£40.4 million. Marquinhos rarely started during the season, due to the partnership of his compatriots Silva and David Luiz in the centre of the PSG defence. One of the team's former defenders, Alex, recommended that Marquinhos leave the team, as he was in demand from big teams in which he would have an opportunity to play. In February 2016, Silva criticised the agency representing Marquinhos and David Luiz for having led two players of the same position to the same club, thus limiting Marquinhos' opportunities; Silva mentioned Barcelona's interest in the player. PSG manager Laurent Blanc stated that he would be open for Marquinhos to leave at the end of the season, while agent Giuliano Bertolucci confirmed that Marquinhos would be leaving.

On 2 March, Marquinhos scored his first goal of the season as PSG won 3–1 at Saint-Étienne in the cup quarter-finals. On 23 April, he played the entirety of a 2–1 win over Lille in the 2016 Coupe de la Ligue Final, and he did so again on 21 May in the Coupe de France final, a 4–2 win over Marseille, as PSG won all four domestic trophies for the second consecutive season.

2016–2020: Sustained domestic success and European final Marquinhos missed PSG's victory in the 2016 Trophée des Champions in August due to his selection in the Brazil team at the Olympics. He was tipped by ESPN journalist Jonathan Johnson to play more frequently over the season, as new manager Unai Emery sold David Luiz back to Chelsea. He scored his first goal of the season on 26 February 2017, opening a 5–1 win at rivals Marseille; prior to the game he confirmed that he was in talks for a new contract at the club. On 26 April, he scored the last goal of a 5–0 home win over title rivals Monaco in the Coupe de France semi-finals, and he started beside Silva in a 1–0 win over Angers a month later in the final. Marquinhos said on 14 May that there was a "100 percent" chance he would remain at the club the following season.

Marquinhos began the 2017–18 season on 29 July, starting as PSG won 2–1 in the 2017 Trophée des Champions at the Grand Stade de Tanger in Morocco. In the team's victorious run in the Coupe de la Ligue, he scored in the 3–2 semi-final win at Rennes on 30 January 2018, but was unused in the 3–0 final win over Monaco as young local Presnel Kimpembe took his place. PSG won all four domestic competitions over the season, and Marquinhos told Le Figaro at the end of the campaign that he would remain at the club.

On 12 August 2020, Marquinhos scored a late equaliser against Atalanta in the Champions League quarter-finals, sparking a late comeback for PSG to win 2–1. On 18 August, he scored in a 3–0 win over RB Leipzig in the semi-finals of the competition, which saw PSG reach the Champions League final for the first time in its history. PSG eventually lost out 1–0 to Bayern Munich on 23 August.

2020–present: Club captain and first Champions League titles

Marquinhos was appointed as PSG's club captain on 15 September 2020, succeeding Thiago Silva in the role. He scored his first goal of the season in a match against Nice five days later. On 2 December, Marquinhos scored the second goal for PSG in a 3–1 win against Manchester United in the UEFA Champions League group stage. In January 2021, he made his 300th PSG appearance in a 2–1 Trophée des Champions victory over Marseille, also entering the club's top ten appearance makers of all time.

On 19 May 2023, Marquinhos signed a new long-term contract at PSG until June 2028, which, if fulfilled, would see him to his fifteenth year at the club. On 6 April 2024, he featured in his 435th match for PSG against Clermont, equaling Jean-Marc Pilorget's record of all-time appearances. Four days later, he surpassed him by appearing in his 436th match against Barcelona in the quarter-finals of the UEFA Champions League.

Marquinhos began the season on 16 August 2024, coming on as a substitute in a 4–1 away win against Le Havre. He played his first Champions League game of the season on 18 September in a 1–0 win against Girona. On 1 February 2025, he featured in his 100th Champions League match in a 3–0 away win over Brest during the knockout play-offs. A month later, on 1 March, he scored his first goal of the season in a 4–1 win against Lille.

Marquinhos captained PSG to their first-ever Champions League title with a commanding 5–0 win over Inter Milan in the final. The victory completed a historic continental treble, as the club had already secured the Ligue 1 title and the Coupe de France.
