Real Madrid Club de Fútbol, commonly known as Real Madrid, is a professional football club based in Madrid, Spain. It is the most successful team in Spanish football and was voted by FIFA as the most successful club of the 20th century, having won a record thirty-one La Liga titles, seventeen Spanish Cups, a record nine European Cups and two UEFA Cups. Real was a founding member of FIFA and the now-defunct G–14 group of Europe's leading football clubs as well as its replacement, the European Club Association.

Founded in 1902, Real Madrid has since spent all of its history in the top flight of Spanish football. In the 1940s, the club, the Santiago Bernabéu Stadium and the Ciudad Deportiva were rebuilt following the Spanish Civil War. The club established itself as a major force in both Spanish and European football during the 1950s. In the 1980s, the club had one of the best teams in Spain and Europe (known as La Quinta del Buitre), winning two UEFA Cups, five Spanish championships in a row, one Spanish cup and three Spanish Super Cups.

The team traditional home colours are all white, although it initially adopted a blue oblique stripe on the shirt. Its crest has been changed several times in attempts to modernise or re-brand; the current crest is a modified version of the one first adopted in the 1920s. Real's home ground is the 80,354-person-capacity Santiago Bernabéu football stadium in downtown Madrid, where it has played since 1947.
