Prince Yi of the First Rank, or simply Prince Yi, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912).
As the Prince Yi 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.
The first bearer of the title was Yongxuan (永璇; 1746–1832), the Qianlong Emperor's eighth son, who was made "Prince Yi of the First Rank" in 1797.
The title was passed down over seven generations and held by seven persons.
