Agrupación Deportiva Alcorcón SAD is a Spanish football team based in Alcorcón, in the autonomous community of Madrid. Founded in 1971, it currently plays in Segunda División, holding home matches at Municipal de Santo Domingo, with a 6,000 seat capacity.
Founded in 1971 by Dionisio Muñoz Jerez, Alcorcón spent roughly its first thirty years in between the fourth division and the regional leagues. In 2000–01, it made its Segunda División B debut, finishing in 12th place, and spending the following seasons immersed in mid-table positions.
In 2008–09, a third place in the regular season meant Alcorcón was allowed to appear in the promotion play-offs for the first time in its history: after disposing of Sant Andreu and Alcoyano, the club was ousted by Real Unión of Irun in the final round with a 3–1 aggregate.
However, in the following season, Alcorcón was finally promoted to level two, after defeating Pontevedra (3–0 on aggregate) and Ontinyent (4–3 on aggregate).
On 27 October 2009, Alcorcón secured the most famous victory in its history, as it defeated La Liga powerhouse Real Madrid 4–0 at home, in the first leg of its round-of-32 match in the Copa del Rey. In the club's first ever official match against a team from the top flight, its opponent fielded nine international players in its starting eleven, lining up: Jerzy Dudek, Álvaro Arbeloa, Raúl Albiol, Christoph Metzelder, Royston Drenthe, Mahamadou Diarra, Guti, Esteban Granero, Raúl, Rafael van der Vaart and Karim Benzema, with Ruud van Nistelrooy, Fernando Gago and Marcelo all appearing in the second half.
On 10 November, in the second leg at the Santiago Bernabéu, the club lost 1–0, but won 4–1 on aggregate, thereby going through to the next round of 16, where the club was ousted by Racing de Santander (2–3 on aggregate).
