is a Colombian professional footballer who plays as a forward for Argentine Primera División club River Plate and the Colombia national team.

Debuting with Deportivo Cali in 2011, he transferred to Cúcuta Deportivo later that year, and then moved to Cortuluá the following year. While remaining contracted to Cortuluá, in 2013, Borja was loaned to La Equidad before joining Serie A club Livorno for his first experience abroad, followed by a loan to Argentine side Olimpo in 2014. He returned to Colombia in 2015, going on loan to Santa Fe, where he was part of the squad that won both the Superliga Colombiana and the Copa Sudamericana. He eventually returned to Cortuluá in 2016, where he had his breakthrough season, emerging as the top scorer in the league during the Apertura, netting 19 goals, which propelled the team to the semi-finals. In June of that year, he transferred to Colombian giants Atlético Nacional, quickly making an impact by scoring four goals in the 2016 Copa Libertadores semi-finals against São Paulo and netting the decisive winning goal in the final against Independiente del Valle to secure the team's second title in the competition, while also finishing as the top scorer with 8 goals in that year's Copa Colombia; a competition he played between Cortuluá and Nacional. His standout performances earned him a spot in the Copa Libertadores Best XI and the prestigious title of South American Footballer of the Year. In February 2017, Borja transferred to Brazilian side Palmeiras on a five-year deal for a reported fee of $10.5 million, making him the fourth most expensive transfer in Brazilian football history. The following year, he won the Campeonato Brasileiro Série A title, finished as the top scorer in that year’s Campeonato Paulista, and was included in the Campeonato Paulista Team of the Year. In December 2019, Borja signed a one-year loan deal with Atlético Junior, where he played a key role in winning the 2020 Superliga Colombiana, scoring a crucial penalty in the first leg and helping secure a 3–2 aggregate victory over América de Cali. After a brief loan spell with Grêmio in 2021, he rejoined Atlético Junior in 2022. In July 2022, Borja moved to Argentine giants River Plate, where he signed a contract running until December 2025. He achieved his first titles with the club in 2023, winning the Argentine Primera División, Supercopa Argentina, and Trofeo de Campeones.

At youth level, Borja was part of the Colombia under-20 squad that won the 2013 South American Youth Football Championship. He also represented Colombia in the 2016 Rio de Janeiro Olympic Games, reaching the quarter-finals. He made his senior debut for Colombia in November 2016 during a 2018 FIFA World Cup qualifier against Chile and scored his first two goals for the national team the following year in a 4–0 friendly win over China. Borja was included in Colombia’s squad for the 2018 FIFA World Cup and participated in the 2021 Copa América, where his country achieved third place, as well as the 2024 Copa América, where they finished as runners-up.
