2019 AFC U-19 Women's Championship

The 2019 AFC U-19 Women's Championship was the 10th edition of the AFC U-19 Women's Championship, the biennial international youth football championship organised by the Asian Football Confederation (AFC) for the women's under-19 national teams of Asia. The tournament was held in Thailand between 27 October and 9 November 2019, with a total of eight teams competing.

The top three teams of the tournament would have qualified for the 2021 FIFA U-20 Women's World Cup (originally 2020 but postponed due to COVID-19 pandemic) in Costa Rica as the AFC representatives. However, FIFA announced on 17 November 2020 that this edition of the World Cup would be cancelled.

This edition was the last to be played as an under-19 tournament, as the AFC had agreed to the proposal for switching the tournament from under-19 to under-20 starting from 2022.

Japan are the defending champions.
