The 2019 AFC Asian Cup was the 17th edition of the AFC Asian Cup, the quadrennial international men's football championship of Asia organised by the Asian Football Confederation (AFC). It was held in the United Arab Emirates from 5 January to 1 February 2019. For the first time, the Asian Cup final tournament was contested by 24 teams, having been expanded from the 16-team format that was used from 2004 to 2015. Under this new format, the finalists would contest a group stage consisting of six groups of four teams, followed by a knockout stage of 16 teams. The host nation qualified for the final tournament automatically, while the remaining 23 places were determined among the other 45 national teams of the AFC through a qualifying competition running from 2015 to 2018, part of which also served as part of the 2018 FIFA World Cup qualification process for the confederation. The tournament was won for the first time by Qatar, who defeated Japan 3–1 in the final. This was also Qatar's first ever top 4 finish in the competition.

However, at its 60th Anniversary celebrations at the end of 2014, AFC gave the date of 'summer 2015' to when an announcement would be made. In January 2015, AFC general secretary Alex Soosay said that Iran and the United Arab Emirates were the only two remaining bidders for the 2019 Asian Cup, and that the eventual hosts would be announced in March 2015. On 9 March 2015, during an AFC Executive Committee meeting in Manama, Bahrain, the United Arab Emirates was announced as the host. This was the second time the country hosted the tournament, after the 1996 edition.
