Paretroplus is a genus of fishes in the cichlid family, all of which are endemic to lakes and rivers of Madagascar. The vast majority are threatened and restricted to the northwestern part of the island. Only P. polyactis is found in the southern half of Madagascar and only P. polyactis and P. gymnopreopercularis are found in eastern drainages. Most are restricted to freshwater, but at least P. polyactis and P. maromandia can also be seen in brackish habitats.

They are more closely related to the genus Etroplus from India and Sri Lanka than they are to other cichlids from Madagascar (subfamilies Paratilapiinae and Ptychochrominae). Their maximum length varies greatly depending on the exact species, ranging from 15–16 centimetres (5.9–6.3 in) in P. kieneri and P. gymnopreopercularis to almost 40 centimetres (16 in) in P. damii.Paretroplus includes both relatively slender-bodied species (P. damii, P. gymnopreopercularis, P. kieneri, P. lamenabe, P. loisellei, P. nourissati and P. tsimoly) and relatively deep-bodied species (all remaining).

There are currently 13 recognized species in this genus. Additionally, an undescribed species from the P. damiiloisellei species group is known from the Ankofia River basin in northwestern Madagascar.
