Notharctus is a genus of adapiform primate that lived in North America during the late to middle Eocene.^[1]

The body form of Notharctus is similar to that of modern lemurs. Its fingers were elongated for clamping onto branches, including the development of a thumb. Its spine is flexible and the animal was about 40 centimetres (16 in) in length, excluding the long tail.^[2]

There were at least four different Notharctus species.^[1] Fossils from at least seven other potential species have also been discovered.
