Xiang Yu's family name was Xiang (項) while his given name was Ji (籍) and his courtesy name was Yu (羽; Yǔ;). He is best known as Xiang Yu.

Xiang Yu is popularly known as the "Hegemon-King of Western Chu" (西楚霸王; Xīchǔ bà wáng). This title is sometimes shortened to "Ba Wang". Since Xiang Yu's death, the term "Ba Wang" has come to refer specifically to Xiang.
