Raranimus is an extinct genus of therapsid of the Middle Permian. It was described in 2009 from a partial skull found in 1998 from the Dashankou locality of the Xidagou Formation, outcropping in the Qilian Mountains of Gansu, China. The genus is the most basal known member of the paraphyletic order Therapsida, from which the class Mammalia is a descendant taxon.
