Asadduzu is a mountain in the range of Zangezur mountains, later in the former Gafan district, and currently in the Syunik province. It is located at a distance of 9 km from the right bank of the Alinja River towards the mountain peak. Its height is 2000 m.

The toponym was coined by combining the word “duz” used in the sense of “a flatland” with the personal name “Asad”.
