Prince Yu of the First Rank (Manchu: ᡥᠣᡧᠣᡳ ᡝᡵᡴᡝ ᠴᡳᠨ ᠸᠠᠩ; hošoi erke cin wang), or simply Prince Yu, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). It was also one of the 12 "iron-cap" princely peerages in the Qing dynasty, which meant that the title could be passed down without being downgraded.
The first bearer of the title was Dodo (1614–1649), the 15th son of Nurhaci, the founder of the Qing dynasty. He was awarded the title in 1636 by his half-brother, Huangtaiji, who succeeded their father as the ruler of the Qing Empire. The peerage was renamed to Prince Xin of the First Rank (Prince Xin) when Dodo's son, Duoni (1636–1661), inherited his father's title in 1649. In 1652, the Shunzhi Emperor downgraded the peerage to Prince Xin of the Second Rank. In 1778, the Qianlong Emperor restored the peerage as "Prince Yu of the First Rank". The title was passed down over ten generations and was held by 14 people: nine as Prince Yu, and five as Prince Xin.
