Ujan is a village in the Echmiadzin uezd of the former Iravan governorate, later in the former Ashtarak district, and currently in the Aragatsotn province. The provincial centre is located 13 km to the northwest of the town of Ashtarak and at a height of 1,150 m above sea level. It was mentioned as “Uchan” in “The Iravan Province Comprehensive Data Book” and marked on the five-verst map of the Caucasus.

The village was solely inhabited by Azerbaijanis: 62 in 1831, 235 in 1873, 364 in 1886, 444 in 1897, 300 in 1908, 318 in 1914, 480 in 1916, 300 Azerbaijanis in 1918. The Azerbaijanis were exposed to the aggression of Armenian armed units and deported in 1919. The Armenians from the Turkish provinces of Bitlis, Arjish and Van were removed and settled in the village. At present, the village is inhabited by Armenians.

The toponym was coined by adding the suffix “-an” to the Turkic ethnonym “Uj” to denote “a place resided by the Uj or the village of the Uj”.

According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative area of the Aragatsotn province.
