Jair Antonio Collahuazo Vaca (born 21 January 2006) is an Ecuadorian professional footballer who plays as a central defender for Kudrivka.
Born in Esmeraldas, Collahuazo began his career in the youth academy of Emelec. Collahuazo's first team debut with Emelec was postponed due to a call-up for a microcycle with the Ecuador under-17 team in September 2023, with teammate Diogo Bagüàdrafted in to cover for an injury crisis instead.
On 29 February 2024, it was reported that New York Red Bulls II had acquired Collahuazo on a one-year loan deal with an option to purchase.
On 11 March 2026, he signed for Kudrivka in Ukrainian Premier League.
Collahuazo was called up to the Ecuador under-17 team for the 2023 South American U-17 Championship, and despite not starting in the first match, established himself as one of Ecuador's key players as the nation finished second place to Brazil.
He was called up again for the 2023 FIFA U-17 World Cup, stating that if his teammates were all focused, they could win the tournament.
Initially a midfielder when he began playing football at the age of eight, Collahuazo was converted to a defender during his career, due to his imposing height â standing at 1.96 m. He has named compatriot Piero Hincapié as an inspiration to him, stating that he hopes to follow in the Ecuador international's footsteps.
