The Spain national under-21 football team is the national under-21 football team of Spain and is controlled by the Royal Spanish Football Federation. The team, nicknamed La Rojita (The Little Red), competes in the biennial UEFA European Under-21 Championship.

Following the realignment of UEFA's youth competitions in 1976, the Spain under-21 team was formed. Spain has a strong record (competition winners five times and runners-up twice); having consecutively won the 2011 and 2013 Championships. They hold the joint record with Italy for the most wins of the competition.

Since the under-21 competition rules insist that players must be 21 or under at the start of a two-year competition, technically it is an U-23 competition. For this reason, Spain's brief record in the preceding U-23 competitions is also shown, though in actuality, Spain played only three competitive U-23 matches. The first was in the "under-23 Challenge", which they lost, while the next two were in a two-team qualification "group" for the 1972 competition (facing the Soviet Union team, they lost 2–1 at home then drew 1–1 away and failed to qualify. Spain did not enter a team in the other two U-23 competitions, but have been ever present in under-21 competitions).

Spain's youth development programs has been challenging the South American dominance in the FIFA U-17 World Championship and the FIFA U-20 World Cup. In fact, 20 of the Spanish 23-man squad that won the Euro 2008 came through the ranks of the youth teams; most of them had won titles at the youth level as well.

Spain U21 is the national youth soccer team of Spain, consisting of players under the age of 21. The team is known for its talented young players who have gone on to become stars in the senior national team and top clubs around the world. Spain U21 has a rich history of success in international competitions, having won the UEFA European Under-21 Championship multiple times. The team is known for its possession-based style of play, quick passing, and technical ability. Spain U21 is seen as a breeding ground for future stars of Spanish soccer and is closely followed by fans and scouts alike.
