2018 AFC U-19 Championship

The 2018 AFC U-19 Championship was the 40th edition of the biennial international youth football championship organised by the Asian Football Confederation (AFC) for the men's under-19 national teams of Asia. It took place in Indonesia, which was appointed as the host by the AFC on 25 July 2017, between 18 October and 4 November 2018. A total of 16 teams played in the tournament.

The top four teams of the tournament qualified for the 2019 FIFA U-20 World Cup in Poland as the AFC representatives. Saudi Arabia won their third title, and qualified together with runners-up South Korea and semi-finalists Qatar and Japan, which were the defending champions but eliminated by Saudi Arabia.

Qualification process
Qualification matches were played between 24 October and 8 November 2017.

Although Indonesia had already qualified automatically as hosts, they also participated in the qualifiers and finished third place after going down 0–3 and 1–4 loss to South Korea and Malaysia sides respectively.

Chinese Taipei returned to the tournament finals for the first time since 1974 as one of the best group runners-up.

The 2018 qualifiers also witnessed a unique situation where two teams had to go to penalties to determine the higher-position team. It happened in Group C after Qatar and Iraq were tied in all tie-breaking criteria and both of them played among each other in the last match. Qatar won the penalties and finished top of the group while Iraq finished second.

Twelve out of 2018 qualified sixteen teams played in the 2016 finals.
