The 2023 FIFA U-20 World Cup will be the 23rd edition of the FIFA U-20 World Cup, the biennial international men's youth football championship contested by the under-20 national teams of the member associations of FIFA, since its inception in 1977 as the FIFA World Youth Championship.
The tournament was originally set to be hosted by Indonesia for the 2021 edition which would have been the first FIFA tournament hosted by that country. But the COVID-19 pandemic forced FIFA to cancel the tournament, who awarded the 2023 hosting rights to the country on 24 December 2020. However, Indonesia was stripped of hosting rights on 29 March 2023 amidst protests at the participation of Israel. On 17 April 2023, FIFA officially announced Argentina as the new host of the tournament to replace Indonesia.
The Dominican Republic and Israel will make their debut in the competition; the Dominican Republic's first ever qualification for a FIFA tournament. Having qualified for the 1970 FIFA World Cup via the Asian qualification, this will be the first FIFA tournament for which Israel has qualified as a European representative.
Argentina qualified for the tournament as host country in place of Indonesia, even though they originally had failed to qualify through the 2023 South American U-20 Championship.
