The Yidgha language (یدغا زڤون) is an Eastern Iranian language of the Pamir group spoken in the upper Lotkoh Valley (Tehsil Lotkoh) of Chitral in the Khyber Pakhtunkhwa province of Pakistan.

The Garam Chashma area became important during the Soviet invasion of Afghanistan because the Soviets were unable to stop the flow of arms and men back and forth across the Dorah Pass that separates Chitral from Badakshan in Afghanistan.

According to Georg Morgenstierne (1931), the name Yidgha probably derives from *(h)ind(a,i)-ka-, likely referring to the part of the Munji tribe that settled on the "Indian" or "Indo-Aryan" side near the Lotkoh Valley.

[3] The Yidgha language has not been given serious study by linguists, except that it is mentioned by Georg Morgenstierne (1926), Kendall Decker (1992) and Badshah Munir Bukhari (2005).

These include Kalasha-mun, Palula, Dameli, Gawar-Bati, Nuristani, Yidgha, Burushaski, Wakhi, Kyrgyz, the Madaglashti dialect of Persian, and Pashto.
