Prince Rui of the First Rank (Manchu: ᡥᠣᡧᠣᡳᠰᠠᠪᡳᠩᡤᠠᠴᡳᠨ ᠸᠠᠩ; hošoi sabingga cin wang), or simply Prince Rui, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912).
As the Prince Rui 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 Mianxin (綿忻; 1805–1828), the Jiaqing Emperor's fourth son, who was made "Prince Rui of the First Rank" in 1819.
The title was passed down over three generations and held by four persons.
