Isisfordia is an extinct genus of crocodyliform closely related to crocodilians that lived in Australia during the Middle Cretaceous (Albian–Cenomanian).

On a later expedition to the location, paleontologists discovered a complete skull which differed from the original specimen in size only.

[6] The discovery of the fossilized remains led paleontologists to suggest that the group including modern crocodilians first evolved 30 million years earlier than previously thought, during the Cretaceous period on the supercontinent Gondwana.

[3] A cladistic analysis by Turner and Pritchard (2015) recovers Isisfordia with Susisuchus in a monophyletic Susisuchidae as a non-eusuchian neosuchian more derived than Dyrosauridae, but more primitive than Goniopholididae.

[7] A 2021 study by Rio and Mannion confirmed the placement of Isisfordia outside of Eusuchia, as the sister taxon to Paralligatoridae.
