The Liechtenstein national under-21 football team represents the under-21s of Liechtenstein in the UEFA U-21 Championship, and is controlled by the Liechtenstein Football Association, the governing body of football in Liechtenstein. On 5 October 2022, it was announced that this team would be dissolved for 2023 and 2024, and would return in time for the UEFA U21-Championship 2027 qualification campaign. This decision was made because most of the higher quality players in this age category would end up playing for the senior team.

The Liechtenstein U21 national soccer team represents the principality of Liechtenstein in international under-21 competitions. As a member of UEFA, the team competes against other European nations in various tournaments, including the UEFA European Under-21 Championship qualifiers.

The squad is composed of talented young players, typically aged 21 and under, who are selected from clubs within Liechtenstein and abroad. The team's development is crucial for nurturing future stars who may eventually represent the senior national team.

Liechtenstein U21 is known for its determination and resilience on the field, often facing larger and more established footballing nations. The coaching staff focuses on developing technical skills, tactical awareness, and teamwork, aiming to foster a competitive spirit and a strong sense of national pride among the players.

While the team may not have a long history of success in international competitions, it serves as an important stepping stone for young athletes aspiring to make their mark in the world of soccer. The Liechtenstein U21 team embodies the hopes and dreams of a small nation, striving to make an impact on the international stage.
