Lü Bu (died February 199) is a military general and later a minor warlord during the late Han Dynasty period of Chinese history.

According to the Records of Three Kingdoms, Lü Bu was highly-skilled in horse-riding and archery, and was thus nicknamed "Flying General".

His image as a handsome and mighty warrior wearing a pheasant-tailed headdress and wielding a ji known as the "Sky Piercer" on top of his steed Red Hare is later popularized by Luo Guanzhong's historical novel Romance of the Three Kingdoms.

In the story, he is considered the single most powerful warrior in all of China.

Besides being matchless on the battlefield, especially in man-on-man duels, Lü Bu is also notorious for having betrayed and slain two separate lords (who were both his adoptive fathers).

He is best known for his amorous relationship with the fictional maiden Diaochan, which eventually caused him to betray and kill Dong Zhuo out of jealousy.

Throughout Romance of the Three Kingdoms, Lü Bu has been depicted as a ruthless and impulsive warrior who has no sense of loyalty and sympathy.

Lü Bu is eventually defeated and captured by Cao Cao at the Battle of Xiapi.

At Liu Bei's suggestion, Cao Cao has Lü Bu hanged.
