Xenocretosuchus is an extinct genus of tritylodonts 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. Both species may be part of the genus Stereognathus.
Alongside Montirictus, it is the latest known non-mammalian synapsid (excepting the perhaps also not-mammalianharamiyidan Avashishta), extending their range to the Early Cretaceous.
