Mirninsky

Mirninsky District is an administrative and municipal district (raion) of the Sakha Republic, Russia. The administrative center is the town of Mirny. The district is located in the eastern part of the republic and includes urban and rural localities.

The district lies in a subarctic climate with long, cold winters and short summers. The terrain features taiga forests and river valleys typical of central Yakutia. It encompasses a variety of geographic features associated with the region's extensive river systems and permafrost zones.

The economy of Mirninsky District is dominated by mining, most notably diamond mining centered on the Mirny Diamond Mine in the town of Mirny. This industry has historically shaped the district’s development. Other economic activities include forestry, construction, and agriculture in rural areas.

The population of the district is sparsely distributed among the administrative center and several rural localities. The demographic composition includes ethnic Yakuts and Russians, with smaller representations of other groups common in the Sakha Republic.

Mirninsky District was established during the Soviet era as part of the administrative framework of the Sakha Republic. The development of the Mirny mine in the mid-20th century played a key role in the district’s growth and urbanization, while the district has since maintained a mixed economy and administrative structure.
