2019 AFC Asian Cup

The 2019 AFC Asian Cup (or commonly called the Asian Cup 2019) was the 17th edition of the men's AFC Asian Cup, the quadrennial international 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, 24 teams competed for the title, replacing the 16-team format 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. It was the first of three consecutive Asian Cups held in Middle East, preceding the 2023 AFC Asian Cup in Qatar and the 2027 AFC Asian Cup in Saudi Arabia.

The tournament was won for the first time by Qatar, who defeated Japan 3–1 in the final. This was Qatar's first ever top-four finish in the competition. Defending champions Australia were eliminated in the quarter-finals by the hosts United Arab Emirates, who subsequently lost to eventual winners Qatar in the semi-finals.

The bidding procedure and timeline for the 2019 AFC Asian Cup was approved at the AFC congress on 28 November 2012. The winning bid was originally set to be announced at an AFC congress in June, then November 2014. 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.

The 2019 AFC Asian Cup qualification process determined the 24 participating teams for the tournament. In 2014, a proposal to merge the preliminary qualification rounds of the FIFA World Cup with those of the AFC Asian Cup was ratified by the AFC Competitions Committee. The new qualification structure took place in three stages, with the first two merging with the 2018 FIFA World Cup qualification In the first round, the lowest ranked teams played home-and-away over two legs to reduce the total number of teams to 40. In the second round, the 40 teams were divided into eight groups of five to play home-and-away round-robin matches, where the eight group winners and the four best group runners-up qualified for the 2019 AFC Asian Cup finals. In the third round, the next best 24 teams eliminated from second round were divided into six groups of four and competed for the remaining slots of the 2019 AFC Asian Cup. The first qualifying round of the qualification took place on 12 March 2015, and the final match of the third round took place on 27 March 2018.

India, Syria, Thailand, and Turkmenistan qualified for the tournament after being absent in several Asian Cup tournaments spanning from 2004 to 2015. Lebanon and Vietnam both qualified for the first time after hosting the tournaments, in 2000 and 2007 respectively. For Vietnam, this was the first time they qualified for the AFC Asian Cup as a unified nation, having participated as South Vietnam in the first two editions (1956 and 1960), outside of hosting the 2007 edition. This was also the first time Yemen qualified for the AFC Asian Cup as a unified country, due to FIFA and AFC categorizing the participation of South Yemen in the 1976 as a distinct record not related to Yemen, who succeeded North Yemen. In addition to Yemen, Kyrgyzstan and the Philippines also marked this edition as their first times to qualify for an Asian Cup.
