Rhodeus rheinardti is a tropical freshwater ray-finned fish belonging to the family Acheilognathidae, the bitterlings. It originates in the Perfume River, near Hué, Vietnam. It was originally described as Danio rheinardti by G. Tirant in 1883.

Named possibly in honor of Pierre-Paul Rheinart (1840-1902), a French official in Hué, Viêt Nam (type locality for this bitterling), who sent zoological specimens to Paris.{{cite web | url = http://www.etyfish.org/cypriniformes14/ | title = Order CYPRINIFORMES: Families ACHEILOGNATHIDAE, GOBIONIDAE and TANICHTHYIDAE | access-date= 3 March 2021 | author1 = Christopher Scharpf | author2 = Kenneth J.

When spawning, the females deposit their eggs inside bivalves, where they hatch and the young remain until they can swim.{{FishBase | genus = Rhodeus | species = rheinardti | year = 2007| month = February }}
