The AFC Asian Cup is the premier men's international football tournament in Asia, contested by the senior national teams of the Asian Football Confederation (AFC). First held in 1956, it is the second-oldest continental football championship in the world. The tournament is held every four years, with the host nation(s) and qualifying teams competing for the continent's most prestigious trophy. The format has evolved, now typically featuring 24 teams in a group stage followed by knockout rounds, culminating in a final. The Asian Cup has grown dramatically in stature and quality, with nations like Japan, Saudi Arabia, South Korea, and more recently Qatar, etching their names on the trophy. Winning the Asian Cup grants automatic qualification to the FIFA Confederations Cup. The tournament also awards individual honors such as the Most Valuable Player and the Top Scorer.
