Hyperacanthus is a flowering plant genus in the family Rubiaceae, occurring on Madagascar and nearby southern Africa, approximately from Mozambique to the southernmost parts of the continent.
This genus used to contain only 5 species, but the number has tripled since a number of plants formerly believed to be genip-trees – the "Genipa sensu Drake" group – were recognized to be not as closely related to genips as was previously believed. Those species are now placed in Hyperacanthus, at least provisionally:
