Boyuk Shahriyar is a village in the Echmiadzin uezd of the former Iravan governorate, later in the former Gurdugulu (Hoktemberyan) district, and currently in the Armavir province. The provincial centre lies 10 km to the southwest of the town of Serdarabad (Hoktemberyan, Armavir), by the canal where the Hrazdan flows, and at a height of 870 m above sea level. It was marked on the five-verst map of the Caucasus.

The village was initially inhabited by Azerbaijanis, who gradually left it, after Armenians had been settled in the region. The Armenians were removed from the Turkish provinces of Van, Ighdir, Tuzluja and the Iranian province of Salmas in 1915–1922 and settled in the village.

The toponym was created by combining the word “boyuk” denoting a distinguishing feature and the personal name “Shahriyar”. It is an anthropotoponym. It was renamed “Nalbandyan” by the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 19 April 1950. 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 Armavir province.
