The CONMEBOL Copa América, known until 1975 as the South American Football Championship, is the world's oldest still-running continental men's football tournament, held quadrennially. Its inaugural edition, the Campeonato Sudamericano de Football, took place in Argentina in 1916, with Uruguay triumphing as the first champion. While primarily contested by the ten CONMEBOL national teams, the tournament has regularly invited nations from North America and Asia since the 1990s, often expanding to 12 or 16 teams for recent events like 2016 and 2024. Notably, the United States is the only non-CONMEBOL country to have hosted the competition. Argentina holds the record for the most championships with 16 titles and has hosted the tournament more times than any other nation, including its historic debut.
