Yinxiang, the Prince Yi (Chinese: 怡親王胤祥; Pinyin: Yìnxiáng; Wade-Giles: Y'in-hsiang; Posthumous name: Xián 賢) (1686 — April 1730) of the Manchu Aisin-Gioro clan was a noble of the Qing Dynasty born as the 13th surviving son to the Kangxi Emperor.

In 1725, Yinxiang was sent to oversee the water issues of Zhili, including flood control and transportation.
Yinxiang received a first-degree princedom and the title Prince Yi from his half brother, who reigned from 1723 to 1735 as the Yongzheng emperor.

After forebears had been dead for more than three generations, they were promoted to the category of "distant ancestors." While displaying portraits of distant ancestors was a way for descendants to honor important kinsmen, they no longer had to dedicate specific rituals to these long-deceased family members.
