Chullu was a village in the territory of the Zangezur uezd of the former Yelizavetpol (Ganja) governorate, later in the former Gafan district, and present-day Syunik province.

The village was inhabited by 109 Azerbaijanis in 1897, 85 in 1904 and 110 Azerbaijanis in 1914. The Azerbaijanis were attacked, massacred or expelled from the village by Armenian armed units in 1918. After the establishment of Soviet power in present-day Armenia, the Azerbaijanis who survived managed to return to their village. The village was inhabited by 39 Azerbaijanis in 1922, 56 in 1926 and 69 Azerbaijanis in 1931. In the 1940s the village was abolished. At present, it lies in ruins.

The toponym was coined by adding the identifying suffix “-lu” to the Old Turkic ethnonym “Chul/Chol” meaning “a place belonging to the Chul tribe”.
