Yunti, born Yinzhen and also known as Yinti before 1722, formally known as Prince Xun, was a Manchu prince and military general of the Qing dynasty. He was trusted by his father, the emperor Kangxi, to lead the imperial forces against the dynasty's greatest threat of the time, the Dzungar Khanate. He proved a successful and popular military leader. He was later imprisoned by the new emperor, who was his full-blood brother – Yongzheng. Yongzheng suppressed the evidences of Yinti's accomplishments and also possible evidences of his right to the throne.

Prince Xun of the Second Rank, or simply Prince Xun, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). As the Prince Xun peerage was not awarded "iron-cap" status, this meant that each successive bearer of the title would normally start off with a title downgraded by one rank vis-à-vis that held by his predecessor. However, the title would generally not be downgraded to any lower than a feng'en fuguo gong except under special circumstances.
