Carpolestes is a genus of extinct primate-like mammals from the late Paleocene of North America. It first existed around 58 million years ago. The three species of Carpolestes appear to form a lineage, with the earliest occurring species, C. dubius, ancestral to the type species, C. nigridens, which, in turn, was ancestral to the most recently occurring species, C. simpsoni.^[1]

Carpolestes had flattened fingernails on its feet but with claws on its fingers.^[2] Morphologically it supports Robert Sussman's theory^[3] of the co-evolution of tropical fruiting Angiosperms and early primates where Angiosperms provide nectar and fruits in return for dispersing the seed for tropical rainforest plants. It appears to have been a distant relative of the Plesiadapiforms such as Plesiadapis.
