Donggao Xinyue was a Chinese Sôtô Zen (C: Cáodòng Chán) Buddhist monk, originally from Hangzhou, who came to reside at a temple in Mito han at the invitation of Tokugawa Mitsukuni, lord of Mito. He is also known for his paintings, calligraphy, and as a talented player of the qin.
Donggao was based for many years at a temple near West Lake in Hangzhou. He was invited to Japan in 1676 by the Ôbaku Zen monk Chengyi Daoliang, and later developed a relationship with Tokugawa Mitsukuni. Through Donggao, Mitsukuni maintained contacts with a number of Ming exiles resident in Japan, even after the death of Zhu Shunsui in 1682.
