Yinxiang, formally known as Prince Yi, was a Manchu prince of the Qing dynasty. The thirteenth son of the Kangxi Emperor, Yinxiang was a major ally of his brother Yinzhen during the latter's struggle for the succession of the throne. He was made a qinwang during Yongzheng's reign and became one of his closest advisors. He died eight years into the reign of the Yongzheng Emperor and was memorialized with top honours by the emperor. When he died, his title was granted "iron-cap" status and became perpetually inheritable, one of the only twelve such princes in Qing dynasty history.
