Juan José Calero Sierra (born 5 November 1998) is a Colombian footballer who plays for Liga MX club Cruz Azul. He also holds a Mexican passport.
Calero was born in Ginebra, Valle del Cauca, Colombia, the son of Colombian goalkeeper Miguel Calero, who spent the bulk of his career at Mexican club Pachuca and represented Colombia internationally. He's father advised him to play as a forward rather than in goal. Calero moved to Mexico as a child and joined Pachuca's youth academy in 2012. His father died in 2012.
Calero made his official debut in September 2015, coming on as a substitute for Jonathan Urretaviscaya in a Copa MX tie against Cruz Azul at Estadio Hidalgo, aged 16.
He made his Liga MX debut on 14 November 2015, in a 2–1 home defeat to Cruz Azul. On 13 August 2016 he scored his first two goals as a professional, coming on as a substitute in the 68th minute — his fourth appearance of the Apertura 2016 tournament — and scoring twice within the next ten minutes as Pachuca beat Pumas UNAM 3–0. The match carried a family echo: Miguel Calero's own final professional appearance, in October 2011, had also come against Pumas.
On 26 April 2017, Calero was part of the Pachuca squad that beat Tigres UANL 2–1 on aggregate to win the 2016–17 CONCACAF Champions League.
In 2018, Calero was loaned to fellow Grupo Pachuca club León.
Calero signed for Mineros de Zacatecas ahead of the Apertura 2019 tournament, following his spells at Pachuca and León. He would go on to be loaned out three times over the following years while registered with the club.
On 1 September 2021, Calero joined Portuguese Primeira Liga side Gil Vicente on a season-long loan. After struggling for minutes, he scored his first goal for the club from the penalty spot in a 2–0 win over Belenenses, his first start for the side.
Calero was loaned to fellow Portuguese club Nacional in 2022.
In 2023, Calero moved on loan to Costa Rican club Sporting San José.
Ahead of the 2025–26 season, Calero signed for Venados of the second-tier Liga de Expansión MX. He finished the Apertura 2025 tournament as the league's top scorer with 15 goals in 15 matches. He added seven goals in the Clausura 2026 tournament before departing the club.
Calero signed for Cruz Azul as a free agent on a two-year contract in July 2026. He was registered as competition for Gabriel Fernández and Nicolás Ibáñez in the forward line and loaned to the club's reserve side, Cruz Azul Hidalgo, in the Liga de Expansión MX.
Calero represented Colombia at under-17 level in 2015, earning five appearances.
Calero holds dual Colombian and Mexican nationality, having been naturalised as a Mexican citizen in 2016. He is the son of Miguel Calero, who died on 4 December 2012.
