The '''Tannu-Ola mountains'''{{efn|{{langx|tyv|Таңды-Уула|Tañdı-Uula}}, {{lang-uniturk|Taᶇdь-Uula}}, {{IPA|tyv|tʰaŋˈtɯ ˈuːla}}}} or '''Tangdy-Uula mountains'''{{efn|{{langx|mn|Тагнын нуруу|Tağnîn nurú}}, {{IPA|mn|tʰaɢˈniŋ nʊˈrʊː}}, {{langx|ru|Танну-Ола}}, {{IPA|ru|tɐnˈnu ɐˈla|}}}} are a mountain range in southern [[Siberia]], in the [[Tuva|Tuva Republic]] of [[Russia]]. It extends in an east–west direction and curves along the [[Mongolia]]n border. Its highest peak reaches {{convert|3061|m|ft|abbr=on}}. The Tannu-Ola mountains are mentioned in the 13th-century text ''[[The Secret History of the Mongols]]'' under the name "Tanglu mountains" ({{lang|zh|唐麓}}), and also in the ''JāmiʿAl-tawārīkh'' of [[Rashid-al-Din Hamadani]] (1247–1318) under the name "Toungat mountains" ({{lang|und|تنغات}}). By the [[Qing dynasty]] the name has been changed to Tangnu ({{lang|zh|唐努}}) mountains, from which the modern name is derived. All names are probably rooted in the old Turkic word ''taŋ'' - "wonder, awe, wondrous."

== Geography ==
The northern slopes are part of the watershed of the [[Yenisei River]], facing the western [[Sayan Mountains]]. The eastern end touches the large watershed of the [[Selenge River]] in [[Mongolia]].
The foothills of the southern slopes cross into Mongolian territory. They form the northern limits of a large basin of [[steppes]] that extends south to the Mongolian [[Altay Mountains]] and includes the salt lake [[Uvs Nuur]]. The western end is located near the northern Altay Mountains in the Russian [[Altai Republic]].<ref>"Tannu-Ola", [[Great Soviet Encyclopedia]]</ref>
