意大利 20岁以下

The Under-20 team is de facto based on the previous year's Under-19 team and acts mainly as a support team for the Under-21 selection, providing further international experience for young selectable players.

The team competes for its only official tournament, the FIFA U-20 World Cup, depending on the U19s results at the UEFA European Under-19 Championship held in the even-numbered years, that qualifies European teams for the U-20 World Cup.

The best result obtained by the Italian team in the U-20 World Cup is the second place achieved in the 2023 edition held in Argentina, losing 1–0 against Uruguay. They finished also third in 2017 and fourth in 2019. Italy managed to qualify for the first time for two consecutive U-20 World Cups after winning its group at the 2018 European U-19 Championship, then finishing fourth at the following year's World Cup.

Each season the team mainly participates in friendly tournaments, in which overage players may also be selected. The U20 team participated until 2017 in the annual Four Nations Tournament with Germany, Switzerland and Poland (which replaced Austria). Since the 2017–18 season, the Italy U20 team participates in the annual Under 20 Elite League, expanded to 8 participants.

The team also had an annual fixture with the Serie D Best XI after the end of the season.
