The name translates from Armenian as "the place of the brave". It is located 356 km away from Yerevan, 25 km away from Kapan, the regional center, and 50 km from the border of Armenia and Iran. Qajaran forms an urban community (municipality). The National Statistical Service of the Republic of Armenia (ARMSTAT) reported its population was 8,498 in 2010, up from 8,439 at the 2001 census.

The area of Kajaran has been occupied by dwellers since the 3rd-2nd millenaries B.C. The pagan temple found in the area testifies that. Metal was processed here since the Bronze Age.

The first copper mines of the area were built in 1850 and worked till 1910. After the discovery of huge copper deposits in 1930, the Soviet government proposed to build a copper-molybdenum plant which was put in service 1952, becoming one of the biggest enterprises of the USSR at that time. Thus, a town was built in the area of Verin Hand and Okhchi villages and its name was derived from the nearby village of Kajarants. The majority of the population of Kajaran were immigrants from Kapan and Karabakh.
