The Lifan Yuan (Chinese: 理藩院; pinyin: Lǐfān Yuàn; Manchu: ᡨᡠᠯᡝᡵᡤᡳᡤᠣᠯᠣᠪᡝᡩᠠᠰᠠᡵᠠᠵᡠᡵᡤᠠᠨ, Möllendorff: tulergi golo be dasara jurgan; Mongolian: Гадаад Монголын төрийг засах явдлын яам, γadaγadu mongγul un törü-yi jasaqu yabudal-un yamun) was an agency in the government of the Qing dynasty of China which administered the empire's Inner Asian territories such as Mongolia and oversaw the appointments of Ambans in Tibet.
The office was initially known as the Mongol Yamen (Chinese: 蒙古衙門; pinyin: Měnggǔ Yámén;[9] Manchu: ᠮᠣᠩᡤᠣᠵᡠᡵᡤᠠᠨ, Möllendorff: monggo jurgan, lit.
In 1639 the department was renamed and expanded to "Lifan Yuan" in Chinese and "Tulergi golo be dasara jurgan" in Manchu.
Prior to the establishment of the Zongli Yamen, the Court also supervised the empire's relation with Russia under the treaties of Nerchinsk and Kyakhta.
Guests of the Lifan Yuan were housed in the Bureau of Interpreters (Chinese: 會同館; pinyin: Huìtóng Guǎn; Wade–Giles: Hui-t'ung Kuan) in the southeast part of the Inner City, later also known as the Russian hostel (Chinese: 俄羅斯館; pinyin: Éluósī Guǎn; Wade–Giles: O-lo-ssu Kuan) due to the predominance of Russian visitors there.
