Aisin Gioro Yicai (奕采, 20 April 1820 - 21 February 1866) was Qing dynasty imperial prince as a biological son of Mianzhi, Prince Yishun of the Second Rank and the third in Prince Qing peerage as an adoptive son of Mianmin.^[1]

Yicai was born on 20 April 1820 to lady An, Mianzhi's mistress.^[2] In 1836, he was adopted as Mianmin's son as all children of the prince Qingliang of the Second Rank died prematurely.^[3] Shortly after the adoption, Yicai inherited Mianmin's title because the peerage was neither promoted to the first rank nor granted a status of qinwang. The promotional ceremony was held at the New Year (除夕夜)^[4]. Around 1842, Yicai was accused of accepting bribes from officials. Daoguang Emperor issued a decree imprisoning him at the Imperial Clan Court together with consorts for further investigation.^[5] His mother was punished by deprivation of her allowance.^[6] As the accusations were confirmed, Yicai was stripped of his title.^[7] The title was later passed to Yikuang, who was finally promoted to the prince of the first rank in 1889.^[8]

Yicai did not recover the previous title.^[9] Nevertheless, he was not granted red girdles because of his later deeds. In 1855, he falsely reported that his elder brother Yiyin guarded the Western Qing tombs.^[10] He was relocated to the capital ^[11] and died on 21 February 1866.

Yicai was initially married to lady Irgen Gioro and later married lady Ulanghan, daughter of Tuo'enduo (拖恩多).
