Mianqin (Chinese: 綿懃; 1768 – 1820) was Qing dynasty imperial prince and Qianlong Emperor's grandson.
Mianqin was born as the eldest son of Yongxing and his primary consort, lady Fuca,[1] niece of Empress Xiaoxianchun (daughter of empress' youngest brother, Fuheng).
[2] Initially Mianqin held a title of lesser bulwark duke.
He became an only heir apparent of the Prince Cheng peerage, because his brothers Miansi and Mianyi were adopted by childless imperial princes, such as Yongzhang or Yongji.
[4] Mianqin was posthumously granted a title of Prince Cheng of the Second Rank in 1820.
