Hillia is a genus of flowering plants in the family Rubiaceae. It has 24 species. All are indigenous to tropical America.
Most of the species are slightly succulent epiphytes or small trees. A few are subshrubs or lianas. Hillia rivalis is a rheophyte. The tissues of all the species contain raphides. The capsules have a beak-like appendage.
Hillia triflora is cultivated as an ornamental.
Hillia was named by Nicolaus Jacquin in 1760. It was named for the English botanist John Hill (1716-1775). Jacquin named only one species, Hillia parasitica. It has been suggested that the specific epithet as well as the generic name might well be a reference to John Hill.
Some authors have placed five of the species in a separate genus, Ravnia. A cladistic analysis of morphological characters found Ravnia to be embedded within Hillia. This hypothesis has not been tested with molecular data.
