Brachyuranochampsa is an extinct crocodilian closely related to, but not within, Crocodylidae.

Although reported from as old as the late Campanian stage of the Late Cretaceous[1], the only robust occurrence of Brachyuranochampsa is B. eversolei from Wyoming [2]. Another species, B. zangerli from the lower Bridger Formation at Grizzly Buttes, has been synonymized with another primitive crocodyloid, "Crocodylus" affinis, also known from the Bridger Formation [3]
