Tregami is a Nuristani language spoken in the villages of Gambir, Kaṭâr, and Devoz in the Tregâm Valley off the lower Pech River[2] in the Watapur District of Kunar Province in Afghanistan.

Tregami belongs to the Nuristani group of the Indo-Iranian language family.

[1] Tregami is a close relative of Nuristani Kalasha, spoken in Ghaziabad District to the east, with which it has a lexical similarity of 75% to 80%.

[1] Although Tregami villages are close in proximity, there is a slight difference between the dialects of Katar and Gambir.

The exonym Tregâm, from Wotapuri-Katarqalai, literally means "three villages", referencing Gambir, Kaṭâr, and Devoz.
