2021 FIFA U-20 World Cup
The 2021 FIFA U-20 World Cup was the planned 23rd edition of the biennial international men's youth football championship organized by FIFA for national teams under the age of 20. It was scheduled to take place in Indonesia from 21 May to 12 June 2021, which would have marked the country's first time hosting a FIFA tournament. The event was cancelled on 24 December 2020 due to the COVID-19 pandemic, and Indonesia was subsequently awarded hosting rights for the 2023 FIFA U-20 World Cup; however, those rights were revoked on 29 March 2023 after Indonesia refused to host Israel.
Ukraine were the defending champions but failed to qualify after the 2020 UEFA European Under-19 Championship was cancelled. The 2021 edition would have been the second U-20 World Cup held in Southeast Asia, following the 1997 tournament, and the first FIFA event in the region since the 2012 FIFA Futsal World Cup.
