The 2011 AFC Asian Cup was the 15th edition of the men's AFC Asian Cup, a quadrennial international football tournament organised by the Asian Football Confederation (AFC). The finals were held in Qatar from 7 to 29 January 2011. It was the second time that the tournament was hosted by Qatar, the previous occasion being the 1988 AFC Asian Cup. Japan won the cup for the record-breaking fourth time after a 1–0 win against Australia, and earned the right to compete in the 2013 FIFA Confederations Cup in Brazil as the representative from AFC.

A television viewing audience of 484 million in 80 countries across the Asia-Pacific region, Europe, North America and North Africa witnessed Japan defeat Australia 1–0 in the final.
