Biarmosuchus is an extinct genus of biarmosuchian therapsids that lived around 267 mya during the Middle Permian period.

The first specimen was found in channel sandstone that was deposited by flood waters originating from the young Ural Mountains.

This genus is abundantly represented, but most of the specimens remain inadequately prepared and have not been used for an anatomical and functional analysis.

Three monospecific genera, Biarmosuchus, Eotitanosuchus, and Ivantosaurus, are known from the Ocher locality, differing dramatically in size.

Ivakhnenko (1999) argues that these represent different growth stages of the same animal but it is now believed the three forms appear to be quite distinct.
