The Selennyakh Range ({{langx|ru|Селенняхский хребет}}, Selennyakhsky Khrebet; {{langx|sah|Силээннээх}}) is a range of mountains in far North-eastern Russia. Administratively the range is part of the Sakha Republic of the Russian Federation.Selennyakhsky Khrebet / Great Soviet Encyclopedia; in 35 vols. / Ch. ed. Yu. S. Osipov. 2004–2017. The town of Deputatsky, capital of the Ust-Yansky District, is located in the area of the range.
Geography
The Selennyakh Range extends from NNW to SSE for almost {{convert|250|km|}} north of the northern end of the Moma Range and east of the Khadaranya Range. It is parallel to the latter and separated from it by the Moma-Selennyakh Depression, a wide intermontane basin, where the river Selennyakh flows and that continues southeastwards along the western side of the Moma Range. The Aby Lowland lies to the east and to the north the Yana-Indigirka Lowland. To the northeast it connects with the Kyun-Tas, at the western end of the Polousny Range, and to the northwest with the far north of the Chersky mountain system.Google Earth
In some works the Selennyakh Range is included as a part of the Chersky Range mountain system.Chersky Range // Great Russian Encyclopedia in 35 vols. / Ch. ed. Yu.S. Osipov . - M , 2004–2017.
The highest point of the Selennyakh Range is the Saltag-Tas (Салтага-Тас), a {{convert|2021|m|ft}} high ultra-prominent ridge located in the southern part, nearly {{convert|90|km|}} to the south of Deputatsky.{{cite web|url=https://www.geoinfo.ru/product/shac-mark-mihajlovich/inzhenerno-geologicheskie-aspekty-osvoeniya-mestorozhdenij-olova-yano-indigirskoj-provincii-s-v-yakutiya-41397.shtml|website=geoinfo.ru|title=Инженерно-геологические аспекты освоения месторождений олова Яно-Индигирской провинции (С-В Якутия) |trans-title=Engineering and geological aspects of the development of tin deposits in the Yano-Indigir province (St. Yakutia)|access-date=2019-11-27}} Other subranges of the wider Selennyakh are the Nemkuchan Range in the northeast —a small ridge along the river of the same name facing the Kyun-Tas, the Esteriktyakh-Tas in the east, and the Tommot Massif and Andrey-Tas at the southern end.Аркадий Андреев, Горы Якутии (Mountains of Yakutia), p. 26
The main rivers of the range are the Uyandina and Selennyakh rivers, both left tributaries of the Indigirka, as well as the Chondon, which flows northwards into the Laptev Sea.

Flora
Permafrost prevails in the area of the range. The river valleys of the range have sparse larch forests, and above {{convert|600|m|ft}} there is a narrow pre-tundra belt in which alder and dwarf cedar predominate. In the higher altitudes there is mountain tundra.
