Koumpiodontosuchus is an extinct genus of neosuchian crocodyliform from the Early Cretaceous Wessex Formation of England. The only species is K. aprosdokiti, named in 2014.

Discovery
The first fossilised fragment of a skull was discovered by Diane Trevarthen on a beach near Sandown on the Isle of Wight in March 2011 and it was initially identified as a juvenile of an unknown Goniopholis species. Three months later, the second fragment of the skull was found by Austin and Finley Nathan. The two fragments were donated to Dinosaur Isle. Megan Jacobs also discovered an isolated tooth belonging to the same genus that was twice the size of those from the holotype. The species that the fragments belonged to was named Koumpiodontosuchus aprosdokiti, meaning "unexpected button-toothed crocodile".

When the fragments were first seen by Steve Sweetman, a palaeontologist with the University of Portsmouth, he thought that they belonged to the Bernissartia fagesii species because of its small size and button-shaped teeth. Sweetman published a paper on the discovery of the new species in Acta Palaeontologica Polonica and it was named and described in 2014.
