Djadochtatherium is a mammal genus that lived in Mongolia during the Upper Cretaceous. It coexisted with some of the late dinosaurs. This animal was a member of the extinct order of Multituberculata. It is within the suborder of Cimolodonta, and a member of the family Djadochtatheriidae. It was named by G.&nbsp;G. Simpson in 1925, the name meaning "Djadokhta beast".

The species Djadochtatherium matthewi was also named by G.&nbsp;G. Simpson in 1925 and has also been known as Catopsalis matthewi (Simpson, 1925). It has been found in the Campanian (Upper Cretaceous)-age Djadokhta and Goyot Formations of Mongolia. This was a relatively large Multituberculate, with a skull length of about 4.5&nbsp;cm. It was originally diagnosed as a species within the North American genus of Catopsalis.
