CONMEBOL Copa América (CONMEBOL America Cup), known until 1975 as the South American Football Championship (Campeonato Sudamericano de Fútbol in Spanish and Copa Sul-Americana de Futebol in Portuguese), is the main men's football tournament contested among national teams from CONMEBOL.
It is the oldest international football competition, and is the third most watched competition. The competition determines the champion of South America. Since the 1990s, teams from North America and Asia have also been invited to participate.
Since 1993, the tournament has generally featured 12 teams – all 10 CONMEBOL teams and two additional teams from other confederations. Mexico participated in every tournament between 1993 and 2016, with one additional team drawn from CONCACAF, except for 1999, when AFC team Japan filled out the 12-team roster, and 2019, which featured Japan and Qatar. The 2016 version of the event, Copa América Centenario, featured sixteen teams, with six teams from CONCACAF in addition to the 10 from CONMEBOL. Mexico's two runner-up finishes are the highest for a non-CONMEBOL side.
Eight of the ten CONMEBOL national teams have won the tournament at least once in its 46 stagings since the event's inauguration in 1916, with only Ecuador and Venezuela yet to win. Uruguay has the most championships in the tournament's history, with 15 cups, followed by Argentina with 14 cups; while the current champion, Brazil, has nine cups. Argentina, which hosted the inaugural edition in 1916, has hosted the tournament the most times (nine).
