The Spain national football team (Spanish: Selección Española de Fútbol) has represented Spain in men's international 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 has participated in a total of 16 out of 22 FIFA World Cups, winning the 2010 edition, and qualifying consistently since 1978. Spain has participated in a total of 12 out of 17 UEFA European Championships, and are the reigning European champions, having won a record fourth title in 2024. After their victory in the 2023 UEFA Nations League they became the second national team, following France, to win three major titles (World Cup, European Championship and Nations League). Spain is also one of only two nations alongside Germany, to have won both women's and men's World Cups.

Having won one World Cup, one Nations League, and three European Championship titles since 2008, Spain is the most successful European national team of the 21st century. The team's achievements from 2008 to 2012 have led many experts and commentators to consider this era's squads one of the best ever teams in football history. During this period, Spain became the first 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. Also in this period from 2008 to 2013, Spain won the FIFA Team of the Year, the second-most of any nation, behind only Brazil. One year before, 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 record for the sport at the time.
