Tirahi () were non-Pashtun Dard people who were the previous inhabitants of Tirah and the Peshawar Valley in modern-day Khyber Pakhtunkhwa, Pakistan. They spoke Tirahi language, a Dardic language of the Kohistani group , which may still be spoken by older adults, who are likewise fluent in Pashto, in a few villages in the southeast of Jalalabad in Nangarhar Province, Afghanistan. The Tirahis were expelled from Tirah by the Afridi Pashtuns. Georg Morgenstierne claimed that Tirahi is "probably the remnant of a dialect group extending from Tirah through the Peshawar district into Swat and Dir."
