Real Madrid Club de Fútbol [reˌalmaˈðrið ˌklubdeˈfuðβol], commonly known as Real Madrid, is a football club from Madrid.

Real Madrid plays in the first Spanish league, the Primera División, and has never been relegated in the entire history of the club. Otherwise, this is only true for Athletic Bilbao and FC Barcelona. Real Madrid is one of the most famous football clubs in the world. With 13 European and UEFA Champions League titles, two UEFA Cup victories and 11 other international titles, the Spanish record holders are the most successful club in Europe and the world. Real Madrid won the first five editions of the European Champion Clubs' Cup from 1956 to 1960 and is the only club to defend the title since the UEFA Champions League was founded. They managed to defend it in 2017 as well as 2018, making it three titles in a row. In recognition of its unique track record at domestic and international level, the club was named 'Best Football Club of the 20th Century' by FIFA in 2000 and 'Best Football Club of the Century to Date' at the Globe Soccer Awards in 2020.

Although Real Madrid was originally founded as a football club, the club also has a basketball section, which is also considered the most successful club in Europe with its eight victories in the European Champion Clubs' Cup, two in the ULEB Euroleague, four in the Cup Winners' Cup and one each in the Korać Cup and the ULEB Eurocup.

Unlike the majority of top European clubs, Real Madrid is neither a corporation nor owned by a private individual. The club, like arch-rivals FC Barcelona, Athletic Bilbao and CA Osasuna, is still wholly owned by its 93,176 club members (socios). Accordingly, the number of memberships is limited by the club's statutes. However, anyone can register for official membership as a fan (Madridista). The number of these currently amounts to over one million.
