Club de Natación Alcorcón was a Spanish swimming and water polo club from Alcorcón, Madrid founded in 1989. Its women's team won both the national championship and the national cup,[1] and it took part in the European Cup, reaching the quarter-finals in 2010.[2] Later that year the club collapsed financially and it was excluded from competition.[3] A new club was subsequently created, CN Ciudad de Alcorcón.
