The Vals Criollo (English: Creole Waltz), or Peruvian Waltz (Spanish: Vals peruano), is an adaptation of the European Waltz brought to the Americas during colonial times by Spain. In the Viceroyalty of Peru, the Waltz was slowly changed to the likings of the Criollo people. In the 20th century, the genre became symbolic of the nation's culture as it gained widespread popularity in the country.
