The Tannu-Ola mountains (Tuvan: Таңды-Уула, Tañdı-Uula, Uniform Turkic Alphabet: Taᶇdь-Uula, IPA: [tʰaŋˈtɯ ˈuːla] – Tangdy-Uula mountains; Mongolian: Тагнын нуруу, Tağnîn nurú, Mongolian pronunciation: [tʰaɢˈniŋ nʊˈrʊː], Russian: Танну-Ола, [tɐnˈnu ɐˈla]) is a mountain range in southern Siberia, in the Tuva Republic of Russia. It extends in an east–west direction and curves along the Mongolian border. Its highest peak reaches 3,061 m (10,043 ft). The Tannu-ola mountains are mentioned in the 13th-century text The Secret History of the Mongols under the name "Tanglu mountains" (唐麓), and also in the JāmiʿAl-tawārīkh of Rashid-al-Din Hamadani (1247–1318) under the name "Toungat mountains" (تنغات). By the Qing dynasty the name has been changed to Tangnu (唐努) mountains, from which the modern name is derived. All names are probably rooted in the old Turkic word taŋ - "wonder, awe, wondrous."
