The Wales national under-21 football team, also known as the Wales U21s, is the national under-21 football team of Wales and is controlled by the Football Association of Wales. The team competes in the UEFA European Under-21 Football Championship, held every two years. To date Wales haven't yet qualified for the finals tournament but in recent years have shown good form, losing in a playoff (5–4) to England in the 2009 qualifying campaign and finishing second in their group two years later, after leading their group until their last game Wales only needed a draw to qualify for the play-offs but lost 1–0 away to Italy.

The under-21 team came into existence following the realignment of UEFA's youth competitions in 1976. A goalless draw in a friendly against England at Wolverhampton Wanderers' Molineux Stadium was Wales U21s' first result.

The national under-21 team is the highest level of youth football in Wales, and is open to any players who were born in Wales or whose parents or grandparents were born in Wales. This team is for Welsh players aged 21 or under at the start of a two-year European Under-21 Football Championship campaign, so players can be, and often are, up to 23 years old. Also in existence are teams for Under-20s (for non-UEFA tournaments), Under-19s and Under 17s. As long as they are eligible, players can play at any level, making it possible to play for the U21s, senior side and again for the U21s.

Wales U21, Wales under-21-fotbollslandslag, är fotbollslandslaget för herrar under 21 år som representerar Wales. Laget styrs av Football Association of Wales och representerar Wales i internationella tävlingar för herrfotboll för spelare under 21 år, som till exempel U21-EM.
