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:

Hyperacanthus ambovombensis Rakotonas. & A.P.Davis
Hyperacanthus amoenus (Sims) Bridson
Hyperacanthus exosolenius (formerly in Genipa, tentatively placed here)
Hyperacanthus grevei Rakotonas. & A.P.Davis
Hyperacanthus lantzianus (formerly in Genipa, tentatively placed here)
Hyperacanthus lastellianus (formerly in Genipa, tentatively placed here)
Hyperacanthus madagascariensis (Lam.) Rakotonas. & A.P.Davis (formerly in Genipa)
Hyperacanthus mandenensis Rakotonas. & A.P.Davis
Hyperacanthus microphyllus (K.Schum.) Bridson
Hyperacanthus perrieri (Drake) Rakotonas. & A.P.Davis (formerly in Genipa)
Hyperacanthus pervillei (Drake) Rakotonas. & A.P.Davis (formerly in Genipa)
Hyperacanthus poivrei (Drake) Rakotonas. & A.P.Davis (formerly in Genipa)
Hyperacanthus ravinensis (Baill. ex Drake) Rakotonas. & A.P.Davis (formerly in Genipa)
Hyperacanthus talangninia (DC.) Rakotonas. & A.P.Davis (formerly in Genipa)
Hyperacanthus tubulosus (formerly in Genipa, tentatively placed here)
