Real Madrid Club de Fútbol (English - Royal Madrid Football Club), commonly referred to as Real Madrid, is a Spanish professional football club based in Madrid.
Real Madrid is considered as one of the biggest and famous football clubs in the world.

The club was founded on 6 March 1902 as the Madrid Football Club, and the club has traditionally worn a white home kit since its inception. The word real is Spanish for "royal" and was bestowed to the club by King Alfonso XIII in 1920 together with the royal crown in the emblem.

Real has played its home matches in Santiago Bernabéu Stadium (81,044-capacity) in downtown Madrid since 1947. Unlike most European sporting entities, Real Madrid's members (socios) have owned and operated the club throughout its history.

Real Madrid was estimated to be worth €3.47 billion ($4.1 billion) in 2018, and it was the highest-earning football club in the world, with annual revenue of €750.9 million in 2018. The club is one of the most widely supported teams in the world. Real is one of three founding members of La Liga that have never been relegated from the top division since its inception in 1929, along with Athletic Bilbao and Barcelona.

The club holds many long-standing rivalries, most notably El Clásico with Barcelona and El Derbi with Atlético Madrid.
