Buir Lake (Mongolian: Буйр нуур, romanized: Buir nuur; Chinese: 贝尔湖; pinyin: Bèi'ěr Hú) is a freshwater lake that straddles the border between Mongolia and China. It lies within the Buir Lake Depression. The Chinese city of Hulunbuir is named after both this lake and Hulun Lake, which lies entirely on the Chinese side of the border in Inner Mongolia.[2]
