Alcorcón (Spanish pronunciation: [alkorˈkon]) is a city in the metropolitan area of Madrid, Spain; As of 2010^[update], it had a population of 168,229. It is located 13 km to the south-west of Madrid.

The site appears to have been inhabited since prehistoric times. The name is of Arabic origin, but little is known of Alcorcón before the Reconquista. An early written reference to Alcorcón is in a medieval document that dates from 28 July 1208. Alcorcón has a small historic centre (including the church of Santa María la Blanca), which is protected as an "archaeological zone". The centre is surrounded by modern developments, as Alcorcón has been growing rapidly in recent times due to migration from other parts of Spain and Latin America.

Alcorcón has two hospitals, the Fundación Hospital de Alcorcón (which is state owned, but run privately), and the Hospital Sur Madrid (a totally private hospital). The Alcorcón campus of the Universidad Rey Juan Carlos teaches health-related courses.

The city is home to the football team Agrupación Deportiva de Alcorcón that plays Segunda División. And also Trival Valderas that plays Tercera División. In addition Club Atletico de Madrid is going to build training facilities in the north of the municipality.
