Ust-Yansky District (Russian: Усть-Я́нский улу́с; Yakut: Усуйаана улууһа, Usuyaana uluuha, IPA: [usujaːna uluːha]) is an administrative[1] and municipal[7] district (raion, or ulus), one of the thirty-four in the Sakha Republic, Russia. It is located in the north of the republic in the Yana River delta on the coast of the Laptev Sea and borders with Allaikhovsky and Abyysky Districts in the east, Momsky District in the south, Verkhoyansky District in the southwest, and with Bulunsky District in the west. The area of the district is 120,300 square kilometers (46,400 sq mi).[3] Its administrative center is the urban locality (a settlement) of Deputatsky.[3] Population: 8,056 (2010 Census);[4] 10,009 (2002 Census);[10] 41,265 (1989 Census).[11] The population of Deputatsky accounts for 37.0% of the district's total population.[4]

In the 2010 census, the indigenous Yakuts again formed a majority of inhabitants, with the total population now just 8,262. In that year, the ethnic composition of the district was:
