Xu Yuanlang (徐圓朗) (died 26 March 623[1]) was an agrarian rebel leader who rose against the rule of the Chinese Sui dynasty late in the reign of Emperor Yang of Sui. After doing so, he did not initially claim any royal title, instead successively submitting nominally to Li Mi the Duke of Wei, Emperor Yang's grandson Yang Tong, Dou Jiande the Prince of Xia, and the Tang dynasty. After Dou was defeated and killed by Tang in 621, Xu briefly re-submitted to Tang, but rose again later that year when Dou's general Liu Heita the Prince of Handong rose against Tang, allying himself with Liu. He claimed the title of Prince of Lu. Tang forces defeated both Liu and Xu in 622, and Xu was killed in flight in 623, ending Xu's state of Lu.

However, Emperor Gaozu's biography in Old Book of Tang dated Xu's defeat to the 5th month of the 7th year of the Wu'de era, corresponding to 23 May to 20 Jun 624 in the Julian calendar.
