The 2025 Copa CONMEBOL Sudamericana was the 24th edition of the CONMEBOL Sudamericana (also referred to as the Copa Sudamericana), South America's secondary club football tournament organized by CONMEBOL. The competition began on 4 March and ended on 22 November 2025, with the final played at Estadio Defensores del Chaco in Asunción, Paraguay. Although Estadio Ramón Tahuichi Aguilera in Santa Cruz de la Sierra, Bolivia was originally selected as the host stadium for the final match, CONMEBOL confirmed the change of host city on 11 September 2025, due to delays in the works to adapt the stadium to host the event.
Argentine club Lanús were the champions, winning their second Copa Sudamericana title after defeating Brazilian side Atlético Mineiro 5âÂÂ4 on kicks from the penalty mark following a 0âÂÂ0 draw after extra time in the final. As winners of the 2025 Copa Sudamericana, Lanús earned the right to play against the winners of the 2025 Copa Libertadores in the 2026 Recopa Sudamericana.
