The Kalash (Kalasha: کالؕاشؕا, romanized: Kaḷaṣa), or Kalasha, are a small Indo-Aryan indigenous people residing in the Chitral District of the Khyber-Pakhtunkhwa province of Pakistan. The term is also used to refer to several distinct Nuristani speaking people, including the Väi, the Čima-nišei, the Vântä, plus the Ashkun- and Tregami-speakers.
According to one Kalash tradition, their ancestors migrated "some centuries ago" to the Chitral Valley from the Waigal Valley, of Nuristan Province, Afghanistan, or from a location further south called "Tsiyam" in their folk songs and epics, possibly near Jalalabad or Laghman in Afghanistan. Another tradition claims descent from the armies of Alexander who were left behind from his armed campaign, though no evidence exists for him to have passed the area.
