Madrid is the capital and most populous municipality of Spain. Madrid has almost 3.3 million inhabitants and a metropolitan area population of approximately 6.8 million. It is the second-largest city in the European Union (EU), second only to Berlin, Germany, and its metropolitan area is the second-largest in the EU. The municipality covers 604.3 km² (233.3 sq mi) geographical area. Madrid lies on the River Manzanares in the central part of the Iberian Peninsula at about 650 m (2,130 ft) above mean sea level. The capital city of both Spain and the surrounding autonomous community of Madrid, it is the political, economic, and cultural centre of the country.

The primitive core of Madrid, a walled military outpost, dates back to the late 9th century, under the Emirate of Córdoba. Conquered by Christians in 1083 or 1085, it consolidated in the Late Middle Ages as a sizeable town of the Crown of Castile. The development of Madrid as an administrative centre was fostered after 1561, as it became the permanent seat of the court of the Hispanic Monarchy. The following centuries were characterised by the reinforcement of Madrid's status within the framework of a centralised form of state-building.

The Madrid urban agglomeration has the second-largest GDP in the European Union. Madrid is ranked as an alpha world city by the Globalization and World Cities Research Network. The metropolitan area hosts major Spanish companies such as Telefónica, Iberia, BBVA and FCC. It concentrates the bulk of banking operations in Spain and it is the Spanish-speaking city generating the largest number of webpages. Madrid houses the headquarters of UN Tourism, the Ibero-American General Secretariat (SEGIB), the Organization of Ibero-American States (OEI), and the Public Interest Oversight Board (PIOB). Pursuant to the standardising role of the Royal Spanish Academy, Madrid is a centre for Spanish linguistic prescriptivism. Madrid organises fairs such as FITUR, ARCO, SIMO TCI and the Madrid Fashion Week. Madrid is home to football clubs Real Madrid and Atlético Madrid.

The origin of the name is unknown. There are various theories regarding the origin of the toponym "Madrid", all of them with problems when it comes to fully explaining the phonetic evolution of the toponym, namely:

Nicknames for Madrid include the plural Los Madriles and La Villa y Corte (lit. 'the town and court').

The site of modern-day Madrid has been occupied since prehistoric times. There are archaeological remains of the Celtic Carpetani settlement, Roman villas, a Visigoth basilica near the church of Santa María de la Almudena and three Visigoth necropolises near Casa de Campo, Tetuán and Vicálvaro.

The first historical document about the existence of an established settlement in Madrid dates from the Muslim age. In the second half of the 9th century, Umayyad Emir Muhammad I built a fortress on a headland near the river Manzanares as one of the many fortresses he ordered built on the border between Al-Andalus and the kingdoms of León and Castile, with the objective of protecting Toledo from Christian attacks from the North and as a starting point for Muslim offensives. After the disintegration of the Caliphate of Córdoba in the early 11th century, Madrid was integrated in the Taifa of Toledo.
