Prince Zheng of the First Rank (Manchu: ᡥᠣᡧᠣᡳ
ᡠᠵᡝᠨ
ᠴᡳᠨ ᠸᠠᠩ; hošoi ujen cin wang), or simply Prince Zheng, 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 Jirgalang (1599–1655), the sixth son of Šurhaci. He was awarded the title in 1636 by his cousin, Huangtaiji, the son and successor of Nurhaci (the founder of the Qing dynasty). When the title was passed down to Jirgalang's son, Jidu (1633–1660), it was renamed to Prince Jian of the First Rank (or simply Prince Jian) and given "iron-cap" status. The title was restored to its original name, "Prince Zheng of the First Rank", during the reign of the Qianlong Emperor (r. 1735–1796). The title was passed down over ten generations, and held by eight princes as Prince Zheng and nine princes as Prince Jian.
