The USA is the defending 3x3 U18 World Cup gold medalist after earning an historic first gold medal at the 2019 FIBA U19 3x3 U18 World Cup. This year's team will be selected following the 2020 USA Basketball 3x3 U18 National Championship, which has been postponed to a later date to be determined due to the COVID-19 pandemic.
The FIBA 3x3 U18 World Cup has been held on an annual basis since 2011, except in the years of the Summer Youth Olympic Games (2010, 2014, 2018, etc.). Twenty men’s and 20 women’s teams are expected to compete in the 2019 event that is being held June 3-7 in Ulaanbaatar, Mongolia. In addition to the men’s and women’s 3x3 tournaments, included in the 2019 3x3 U18 World Cup program will be skills contests, giving athletes chances to win additional medals.
