Gilchristosuchus (meaning "Gilchrist [the owners of the ranch where the type specimen was found] crocodile") is an extinct genus of neosuchian crocodyliform. Its fossils have been found in the upper Milk River Formation of Alberta, Canada, in rocks of either latest Santonian or earliest Campanian age (Late Cretaceous). Gilchristosuchus was described in 1993 by Wu and Brinkman. The type species is G. palatinus, in reference to its distinctive palatine bones.
