James Peter Geiss was an American scholar who published several books and articles on Chinese history, specifically on the Ming dynasty.
A graduate of Williams College and Princeton University, he completed his doctoral dissertation, Peking under the Ming in 1979.
He published two chapters in volume 7 of The Cambridge History of China, focusing on the history of the Ming dynasty. His contributions "The Cheng-Te Reign" and "The Chia-Ching Reign" were complemented by the more specialized studies "On the significance of the reign title Chia-ching" and "The Leopard Quarter during the Cheng-te reign", both in Ming Studies. He published the latter in the Chinese language as "Ming Wuzong yu Baofang" in the Palace Museum Journal, an article taken very seriously by Chinese scholars. He collaborated with Chu Hung-lam to translate original Chinese texts for Louise Levathes's popular book, When China Ruled the Seas.
