Euclea sekhukhuniensis Retief Siebert & A.E.van Wyk, a new species with a restricted range in Sekhukhuneland, South Africa. is described, illustrated and compared with other members of the genus. It is a gregarious geoxylic suffrutex forming large, much-branched colonies. The species is closely related to the small tree/shrub E. linearis Zeyh. ex Hiern from which it can be distinguished by its larger fruits, broader leaves and exclusively suffrutex growth form. Geographical range and habitat preference also differ between the two taxa. E. sekhukhuniensis is endemic to the Sekhukhuneland Centre of Plant Endemism, where it is confined to the calcareous, heavy-metal soils of the Steelpoort River Valley.
