Maratuz was a village in the Sharur-Daralayaz uyzed of the former Iravan governorate, later in the former Pashali (Azizbeyov, Vayk) district, and currently in the Vayots Dzor province. İt was located near the Kilsabulag River, the right tributary of the Julchay. Another name for the village was Maratuk. The village was noted as “Maradik” in “The Iravan Province Review book” and as “Maratuz” on the five-verst map of the Caucasus and also as “Maratuz gishlaghi” in other sources.

The village was solely inhabited by Azerbaijanis: 32 in 1831, 166 in 1873, 220 in 1886, 242 in 1897, 284 in 1904, 273 in 1914 and 321 Azerbaijanis in 1916. The Azerbaijanis were attacked, massacred or ousted from the village by Armenian armed units in 1918. Later, the village was abolished. At present, it lies in ruins.

The toponym was coined by combining the words “mara” meaning “a hill” in Turkic and “tuz/duz” meaning “salinity, saline lands”.
