Helian Bobo (381–425), née Liu Bobo , courtesy name Qujie, formally Emperor Wulie of Xia, is the founding emperor of the Chinese/Xiongnu state Xia.

He is generally considered to be an extremely cruel ruler, one who betrays every benefactor that he has, and whose thirst for killing is excessive even for the turbulent times that he is in.

He builds an impressive capital for his state at Tongwancheng (in modern Yulin, Shaanxi) that remains difficult to besiege, even hundreds of years later during the Five Dynasties and Ten Kingdoms Period.

(Confusingly, the Book of Wei refers to him as Helian Qugai, based on a derogatory term that Emperor Taiwu of Northern Wei used to refer to him.)
