Jamsrangiin Tseveen (Mongolian: Жамсрангийн Цэвээн; Russian: Tsyben Zhamtsaranovich Zhamtsarano; often romanized to Jamtsarano), (1880 - May 14, 1942) was a Buryat scholar and one of the leading figures in Mongolian politics and especially academia in the 1920s.
Tseveen was born in the Aginsk district of Transbaikalia in 1880. He went to school in Chita and later to Badmaev's Buryat private school in St. Petersburg. From 1898 to 1902, he attended the Teacher's seminary in Irkutsk, where he began to visit neighbouring Buryat clans and to collect epics and materials related to shamanism, and Mongol law.
In 1902 he and his friend Baradin returned to St. Petersburg and became auditors at the St. Petersburg University. A professor arranged for them to travel to Buryatia in 1903 to collect more material. Tseveen went to the northwest Baikal area and Olkhon island, and his work proved successful enough to earn him more research trips over the next years, sponsored by the Russian Committee for the Investigation of Central and Eastern Asia. In 1904 he travelled to Urga and home to Aginsk, in 1905 and 1906 he again travelled to Transbaikalia and Outer Mongolia. From 1907 to 1908 he taught Mongolian at the St. Petersburg University's Faculty of Oriental Languages. In 1909 and 1910 travelled to Inner Mongolia and the Ordos area. In 1911, he travelled to the Tungus at the upper Onon river, and in 1912 he took part in archeological studies at Erdene Zuu, the former site of Karakorum.
