Coelognathosuchia is an extinct clade of neosuchian crocodyliforms that includes all taxa more closely related to the family Pholidosauridae than to Bernissartia fagesii or Eusuchia.

Martin et al. (2014) named the clade after finding goniopholidids and pholidosaurids to group together in their phylogenetic analysis of crocodyliform evolutionary relationships.

[1] Martin et al. named Coelognathosuchia from the Greek κοῖλος (koĩlos, "concave"), γνάθος (gnáthos, "jaw") and σοῦχος (soũchos, "crocodile"), after a small depression on the surface of the skull between the maxilla and jugal bones in both goniopholidids and pholidosaurs.

Other diagnostic features of Coelognathosuchia include orbits (eye sockets) that are narrower than the frontal bone that separates them and smaller than the supratemporal fenestrae (two holes at the back of the skull roof) behind them, a notch between the premaxilla and maxilla at the tip of the snout, and the reduction or absence of the antorbital fenestrae (a pair of holes in the snout in front of each orbit).

In their description of Pholidosaurus specimens from southwestern France, Martin and colleagues reiterated their opinion that Dyrosauridae is not as closely related to Pholidosauridae as stated by previous authors by pointing to numerous shared characters between the Cherves-de-Cognac pholidosaurid remains and Goniopholididae.
