João Fonseca defeated Francisco Cerúndolo in the final, 6–4, 7–6(7–1) to win the singles tennis title at the 2025 Argentina Open.[1] He saved two match points (in the quarterfinals against Mariano Navone) en route to his first ATP Tour title. Fonseca was the youngest Brazilian man and the second-youngest South American in the Open Era, behind only Guillermo Pérez Roldán in 1987, and the first man born in 2006, to win a top-level title.[2] He entered the tournament through the Next Gen Accelerator Program introduced by the ATP in 2024, being the first player entered under the system to win a tour-level title. Fonseca was the first Brazilian man to win the Argentina Open title since Gustavo Kuerten in 2001, and the lowest-ranked champion (world No. 99) in tournament history.[3]

Facundo Díaz Acosta was the defending champion,[4][5] but lost in the first round to Thiago Seyboth Wild.[6]

This tournament marked the final professional appearance of former world No. 8 Diego Schwartzman.[7] He defeated seventh seed Nicolás Jarry in the first round,[8] before losing in the second round to Pedro Martínez.[9]
