The Campeonato de España–Copa de Su Majestad el Rey, commonly known as Copa del Rey, La Copa or (in English) the Spanish Cup, or Cup of the King, and formerly known as Copa del Presidente de la República (1932–36) and Copa del Generalísimo (1939–76), is an annual knockout football competition in Spanish football, organized by the Royal Spanish Football Federation. The competition was founded in 1903, thus making it the oldest Spanish football competition played at a national level. Copa del Rey winners qualify for the following season's UEFA Europa League.
