'''''Cynodonichthys''''' is a genus of freshwater killifish in the family Rivulidae. They are found in Middle America, ranging from southern Mexico (north to Oaxaca and the Yucatán Peninsula), through Central America (where most species live), to Colombia (in the northwest and the Magdalena River basin).<ref name=Costa2011>{{cite journal| author=Costa, W.J.E.M. | year=2011 | title=Phylogenetic position and taxonomic status of Anablepsoides, Atlantirivulus, Cynodonichthys, Laimosemion and Melanorivulus (Cyprinodontiformes: Rivulidae) | journal=Ichthyological Exploration of Freshwaters | volume=22 | issue=3 | pages=233–249 }}</ref><ref name=Vermeulen2013>Vermeulen, F.B.M.
