Rudolf Mansfeld (17 January 1901, Berlin – 1960) was a German botanist and agricultural scientist.
For more than twenty years, he served as a curator at the Botanical Garden and Botanical Museum in Berlin-Dahlem, where he specialized in the study of Orchidaceae (orchids) and Euphorbiaceae (spurges). After World War II, by way of a request from agriculturalist Hans Stubbe (1902–1989), he accepted a position as a laboratory technician at the Gatersleben Institute. In 1949, he succeeded Werner Rothmaler (1908–1962) as departmental director. During his last ten years at Gatersleben, he was in charge of the department of systematics.[1]
