Cichlidogyrus is a genus of monopisthocotylean monogeneans in the family Ancyrocephalidae.

The type-species of the genus is Cichlidogyrus arthracanthus Paperna, 1960, by original designation.

[1] All the species of the genus are parasites on the gills of fish, namely African Cichlidae, Nandidae and Cyprinodontidae.

[1] [2] [3] [4] [5] [6] [7] [8] Species of Cichlidogyrus are parasitic in many cichlid species in the Lake Tanganyika; a recent study (2016) has shown that species which are parasite on deep-water fish show reduced parasite-host specificity in comparison to species from littoral waters, probably an adaptation to low host availability.

Nikol Kmentová, Milan Gelnar, Stephan Koblmüller and Maarten P.M. Vanhove estimated that the number of species was more than 100 in 2016[10] and Chahrazed Rahmouni, Maarten P. M. Vanhove and Andrea Šimková listed 111 species in 2017.
