Xenocretosuchus is a genus of tritylodont therapsids from the Aptian (Early Cretaceous) of Siberia, in the Russian Federation. The type species, X. sibiricus, is known only from dental elements, as is X. kolossovi, described in 2008.
Alongside Montirictus, it is the latest known non-mammalian synapsid (excepting the perhaps also not-mammalian haramiyidan Avashishta), extending their range to the Early Cretaceous.
