Els carpolèstids (Carpolestidae) és una família de plesiadapiformes semblants a primats que visqueren a Nord-amèrica i Àsia des de mitjans del Paleocè fins a principis de l'Eocè. Es caracteritzen típicament per dos premolars posteriors superiors grans. Pesaven uns 20–150 g i tenien la mida aproximada d'un ratolí. Tot i que formen part de l'ordre dels plesiadapiformes, que podrien haver originat els primats, els carpolèstids eren massa derivats i especialitzats per ser-ne els avantpassats.

Carpolestidae is a family of primate-like Plesiadapiformes that were prevalent in North America and Asia from the mid Paleocene through the early Eocene. Typically, they are characterized by two large upper posterior premolars and one large lower posterior premolar. They weighed about 20-150g, and were about the size of a mouse. Though they come from the order, Plesiadapiformes, that may have given rise to the primate order, carpolestids are too specialized and derived to be ancestors of primates.
Historically, the almost twenty species included within the family were thought to have given rise to each other over time in a linear and straightforward manner. Still today it is widely assumed that Elphidotarsius from the mid to late Paleocene gave rise to Carpodaptes which lived in the late Paleocene and subsequently gave rise to Carpolestes from the early Eocene. As a result, they have been used as biostratigraphic indicators in a variety of paleontological digs. However, the phylogenetic picture has been complicated by the discovery in Asia of both ancestral and derived carpolestids in the same stratigraphic layer.

Los carpoléstidos (Carpolestidae) son una familia de mamíferos plesiadapiformes similares a primates que vivieron en Norteamérica y Asia desde mediados del Paleoceno hasta principios del Eoceno. Se caracterizan típicamente por dos premolares posteriores superiores grandes. Pesaban unos 20-150 gr y tenían el tamaño aproximado de un ratón. Aunque forman parte de la orden de los plesiadapiformes, que podrían haber originado los primates, los carpoléstidos eran demasiados derivados y especializados para ser los antepasados directos.
Se ha propuesto que está relacionado con los primates y los otros plesiadapiformes de la siguiente manera, en el cladograma puede notarse que son el grupo hermano de los primates y posiblemente sean sus precursores directos:[1]
