Catopsalis is a genus of extinct mammal from the Paleocene of North America.

At one time, the genus was also formally reported from the upper Cretaceous of Mongolia.

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

This species has been found in Puercan (Paleocene)-age strata of the San Juan Basin of New Mexico and in the Ravenscrag Formation of Canada.

It has been found in the Torrejonian (Paleocene)-age beds in the San Juan Basin of New Mexico and Utah.

It is found in the Puercan (Paleocene)-age Littleton Local Fauna of Colorado, Montana and Wyoming (United States), dating from 66 - 63 million years ago.
