Canis apolloniensis is an extinct species of Canidae which was endemic to Europe and lived during the Early Pleistocene epoch from 1.81 Mya—781,000 years ago, existing for approximately 1.1 million years. Canis apolloniensis was a short-lived species in geologic time when compared to other Canis species. It coexisted with the Eurasian wolf which appeared 1.59 million years earlier at 3.4 Ma. Canis apolloniensis was named by Koufos and Kostopoulos 1997. The only fossil reference comes from northern Greece
