Möngün-Taiga, also known as Mungun-Taiga (Tuvan: Мөңгүн-Тайга - Silver Mountain) is a massif in Mongun-Taiga kozhuun, Russia. The Russian part of the Altai Mountains is considered part of Western Siberia, but Möngün-Taiga in 1932 was transferred (along with the north of Uvs Nuur Basin) from the Mongolian People's Republic of Tuva, and in 1944 became part of Eastern Siberia.
