Adapidae
}}
Adapidae is a family of extinct primates that primarily radiated during the Eocene epoch between about 55 and 34 million years ago.
Adapid systematics and evolutionary relationships are controversial, but there is fairly good evidence from the postcranial skeleton (everything but the skull, or cranium) that adapids were stem strepsirrhines (members of the group including the living lemurs, lorises, and bushbabies). In particular, the anatomy of the adapid wrist and ankle (e.g., position of the groove for the flexor fibularis tendon on the talus, the presence of a sloping talo-fibular facet) show derived similarities with those of living strepsirrhines. However, adapids lacked many of the anatomical specializations characteristic of living strepsirrhines, such as a toothcomb,〔Fleagle, J. G. 2000.

There are two major branches of adapids, subfamily Adapinae (adapines) and subfamily Caenopithecinae (caenopithecines). Caenopithecines are sometimes assigned to their own family, Caenopithecidae.
