The Spain national football team (Spanish: Selección Española de Fútbol) has represented Spain in international men's football competitions since 1920. It is governed by the Royal Spanish Football Federation, the governing body for football in Spain.

Spain is one of eight national teams to have been crowned world champions and have participated in a total of 16 of 22 FIFA World Cups, also qualifying consistently since 1978. Spain have won three continental titles during their appearances of 11 out of 16 UEFA European Championships. Spain currently competes in League A of the UEFA Nations League alongside the other top teams of Europe. Their best result was in the 2022–23 season where they reached the final, winning against Croatia.

Spain's achievements from 2008–2012 have led many experts and commentators to consider this era's Spain squads one of the best ever teams in football history. During this period, Spain became the only national team to win three consecutive major titles, including two back-to-back European Championships in 2008 and 2012, while becoming the first European team to win a World Cup held outside of Europe in 2010. From 2008 to 2013, Spain won the FIFA Team of the Year, the second-most of any nation, behind only Brazil. From the start of 2007 to the 2009 FIFA Confederations Cup, Spain achieved 35 consecutive undefeated matches, a feat which they shared with Brazil, and a sport record at the time. Spain along with France are the only two European countries to have won the triplete (World Cup, Euro, Nations League).

Spain is one of only two nations to have won both the FIFA World Cup and the FIFA Women's World Cup (the other being Germany).
