Kalai Kafirnigan, also Kala-i Kafirnigan was a Buddhist temple in the region of Tokharistan (Classical Bactria), dated to the 7th-8th century CE. Buddhism in Tokharistan is said to have enjoyed a revival under the Western Turks (known as Tokhara Yabghus in Tokharistan). Several monasteries of Tokharistan dated to the 7th-8th centuries display beautiful Buddhist works of art, such as Kalai Kafirnigan, Ajina Tepe, Khisht Tepe or Kafyr Kala, around which Turkic nobility and populations followed Hinayana Buddhism.
