The Kalasha , or Kalash, also called Waigali or Wai, are an Indo-Aryan indigenous people residing in the Chitral District of Khyber-Pakhtunkhwa province of Pakistan. They speak the Kalasha language, from the Dardic family of the Indo-Aryan branch. The neighbouring Nuristani people of the adjacent Nuristan (previousely known as Kafiristan) province of Afghanistan once had the same culture and practised a faith very similar to that of the Kalash, differing in a few minor particulars.

The Kalash practice a religion which some authors characterise as a form of animism, while academics classify it as a form of ancient Hinduism. During the mid-20^th century an attempt was made forcibly to convert to Islam but the people fought the conversion. Nevertheless, so many have now converted that today over half of the Kalasha are Muslim, with a sizeable minority continuing to practice their native religion.
