Liu Meng (died February or March 272[1]) was a leader of the Southern Xiongnu in Bing province during the Jin dynasty (266–420).
[3] A memorial sent by the Cao Wei general, Deng Ai in the 250s indicates that after Qubei's death, his son was not allowed to inherit his domain.
To curb the growing power of the Xiongnu leader, Liu Bao at the time, Deng recommended for Qubei's son to be given a title and garrisoned at Yanmen Pass.
At the end of the year, he led his forces to invade Bing province but suffered defeat to the provincial inspector, Liu Qin (劉欽).
In spring 272, the Army Supervisor, He Zhen, campaigned against Liu Meng and defeated him multiple times.
