Prince Qin of the Second Rank, or simply Prince Qin, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). As the Prince Qin 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. The peerage was created in 1684 for Yunduan, Nurhaci's great-grandson and son of Yolo, Prince An of the Second Rank.
