Prince Yu of the First Rank, or simply Prince Yu, was the title of a princely peerage used in China during the Manchu-led Qing dynasty. As the Prince Yu peerage was not awarded "iron-cap" status, this meant that each successive bearer of the title would normallystart off with a title downgraded by one rankvis-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. The first bearer of the title was Fuquan, the Shunzhi Emperor's second son. In 1667, Fuquan was granted the title "Prince Yu of the First Rank" by his third brother, the Kangxi Emperor. The peerage was passed down over ten generations and held by 12 persons.
