Scardinius graecus, also called the Greek rudd or Yliki rudd, is a species of cyprinid fish, that is endemic to a single lake, Lake Yliki, in Greece.

The other known population, in Lake Paralimni, disappeared after the lake had been drained.

This fish is classified as a Vulnerable species.

Populations have been introduced to the artificial reservoirs Lake Marathon and Lake Beletsi to the north of Athens.
