"Liotomus" is a genus of extinct mammal from the Paleocene epoch (early Cenozoic era). It lived in Europe and North America, and was a member of the extinct order Multituberculata, lying within the suborder Cimolodonta and possibly the family Cimolodontidae.

The genus "Liotomus" was named by E. D. Cope in 1884. It has also been known as "Neoctenacodon" (Lemoine 1891); "Neoplagiaulax" (partly); and "Parectypodus" (partly). This genus is sometimes placed within family Eucosmodontidae (Jepsen 1940).

"Liotomus marshi"

* Described by: Lemoine, 1882; Cope, E.D., 1884
* Alternate names: "Neoctenacodon marshi" and "Neoplagiaulax marshi")
* "L. marshi" remains are known from the Upper Paleocene of Cernay, France.
* "L. marshi" has been cited as a descendant of "Anconodon gidleyi".

"Liotomus vanvaleni"

* Alternate names: "Parectypodus vanvaleni" (Sloan RE, 1981), "Ptilodus sinclairi")
* "L. vanvaleni" remains are known from the San Juan Basin, New Mexico.
