Craterocephalus eyresii, the Lake Eyre hardyhead, is a species of freshwater silverside from the family Atherinidae which is endemic to the Lake Eyre basin in Australia. Until the late 20th century, this taxon was more widely circumscribed. After it was revealed to be a cryptic species complex, C.eyresii was split up into four species – apart from the Lake Eyre hardyhead proper, these are the Darling River hardyhead (C. amniclus), Finke River hardyhead (C. centralis), and Murray hardyhead (C. fluviatilis), each of the four being restricted to their namesake river basins.
