Sergio Ezequiel Araujo (born 28 January 1992), nicknamed El Chino, is an Argentine professional footballer who plays as a forward for Paraguayan Primera División club Cerro Porteño.

He played his first match as a professional on 13 December 2009, coming on as a late substitute for Nicolás Gaitán in a 0–2 home loss against Banfield for the Primera División championship.

On 25 July 2012, Araujo moved abroad for the first time in his career, signing a two-year loan deal with Barcelona and being assigned to the reserves in Segunda División.

[10] Las Palmas came fourth and made the play-offs, in which Araujo opened a 1–1 draw at Real Valladolid in the first leg of the semi-finals; he missed a penalty in added time in the goalless second as his team advanced on the away goals rule.

On 21 June 2015, in the final second leg against Real Zaragoza at the Estadio Gran Canaria, he scored an 84th-minute goal that made it 2–0 on the night, 3–3 on aggregate, thus sending Los Amarillos into La Liga via the same rule.

Despite strong links to a move to Celtic[12] and Real Sociedad[13] the club managed to buy him outright, with the player signing a five-year deal.

However, there is a reported clause in the deal which means that if AEK didn't decide to purchase Araujo on a permanent basis for €2.7 million after the campaign ends, they will have to pay a hefty compensation fee to Las Palmas.

[26] On 9 February 2020, Araujo scored his first goal since rejoining AEK, after eight minutes of a 1–0 win over city rivals Panathinaikos at the Olympic Stadium in the Super League Athenian derby.

[30] On 6 February 2022, Araujo scored a brace, celebrating his 100th appearance with the club and named MVP in a 3–0 home win game against Apollon Smyrnis.

The club was allowed to sign him outside of transfer window on an emergency replacement clause, after Tobías Portillo suffered an injury with the Paraguay under-20 national team.
