The next Youth Men's and Women's World Championships are set to take place in the Polish city of Kielce from April 13 to 24, 2021.
The world's best boxers aged 17 and 18 will be competing across 10 weight classes.
AIBA was due to host the event between November 2 and 9, 2020, but it was postponed due to the coronavirus pandemic.
Bouts in 2021 will take place at the Hala Legionow Sports Complex, with space for 3,000 fans.
Poland saw off competition from rival bidder Nicaragua to earn the right to host the event.
It will be the first time the country welcomes the tournament.
Men and women will compete alongside each other for the second Youth World Championships in a row, having done so in the Hungarian capital of Budapest in 2018.
There, 359 boxers from 65 countries battled for the title.
Russia finished as the most successful country, earning six gold medals.
Boxers from the United States claimed three gold medals between them, while Thailand and India got two golds each.
The Youth World Championships are a biennial competition, with the first edition held in 1979 in Yokohama in Japan.
It was originally called the Junior World Championships, before switching to its new name in 2008, when the event was held in the Mexican city of Guadalajara.
