The Acciona Open de España is the national open golf championship of Spain. It was founded in 1912 and has been part of the European Tour's schedule since the inception of the Tour in 1972. The tournament has been played in April or May, except for a five-year period in the early 1980s and since the 2019 edition, when the tournament was moved to October. In 2005, it was one of five European Tour events to be held in Spain. Former champions include Arnold Palmer, Seve Ballesteros, Bernhard Langer, Nick Faldo and Jon Rahm.
