Yishiha (; also rendered as Išiqa and Isiha; Jurchen: 60px ) (fl. 1409–1451), sinicized name Yi Xin (易信), was a Jurchen eunuch of the Ming dynasty of China. He served the Ming emperors who commissioned several expeditions down the Songhua and Amur Rivers during the period of Ming rule of Manchuria, and is credited with the construction of the only two Ming dynasty Buddhist temples ever built on the territory of present-day Russia.
