Catopsalis is a genus of extinct mammal from the Paleocene of North America. This animal was a relatively large member of the extinct order of Multituberculata. Most multituberculates were much smaller.

At one time, the genus was also formally reported from the upper Cretaceous of Mongolia. However, that material was subsequently referred to the genera of Djadochtatherium and Catopsbaatar. Catopsalis is within the suborder of Cimolodonta and a member of the superfamily Taeniolabidoidea.

Recent research suggests that "Catopsalis" is actually a paraphyletic assemblage, and one species, C. joyneri, has been moved to its own genus, Valenopsalis.^[1]
