Phillips Foster Greene (May 30, 1892 – April 11, 1967) was an American doctor who, in collaboration with the Yale-China Association, pioneered medical missions to China from 1923 to 1943, and to Burma from 1951 to 1953. Greene was most known for his contribution to the Chinese health system through his leadership of the Hsiang-Ya Medical School, and as Director of the American Red Cross in China. In addition to evangelical motives, he focused especially on sustainability and collaboration with local groups, a concept not to be widely considered until decades later.
