Uchduz was a winter pasture located in the territory of the Zangazur uezd of the former Yelizavetpol (Ganja) governorate, later in the former Mehri (Meghri) district, and present-day Syunik province.

The toponym was formed on the basis of the word “uch” denoting a number and the word “duz” which denotes a relief.
