Leucos ylikiensis is a species of freshwater fish in the family Cyprinidae. It is found only in Greece, in the Kifissos drainage and Lake Yliki. The other known population, in Lake Paralimni, was extirpated when the lake was drained. L. ylikiensis was described as a distinct species in 1991. It is threatened by habitat loss.
