Xiao Zhengde (蕭正德) (died 8 August, 549[1][2]), courtesy name Gonghe (公和), was an imperial prince and briefly a pretender to the throne of the Chinese Liang Dynasty.
In 522,[3] he fled to rival Northern Wei, claiming to be Liang's deposed crown prince, and sought military assistance.
After Xiao Zhengde's return to Liang, however, he did not regret his actions, but instead gathered thugs, often leading them in robberies.
In 525, Xiao Zhengde was a general under the command of Emperor Wu's son Xiao Zong (蕭綜) the Prince of Yuzhang, defending the city of Pengcheng, which was surrendered to Liang by the Northern Wei general Yuan Faseng (元法僧) earlier that year.
Because of crimes he had previously committed and because of his abandoning his forces, Emperor Wu stripped Xiao Zhengde of his title and offices and exiled him to Linhai.
He created his heir apparent Xiao Jianli (蕭見理) crown prince, and married a daughter to Hou.
He also made a pact with Hou that when the palace fell, Emperor Wu and Xiao Gang would not be spared.
