Pteronarctos is a genus of basal pinnipediform from middle Miocene marine deposits in Oregon.

Two species of Pteronarctos are known, P. goedertae and P. piersoni. Although originally described as a member of Enaliarctidae, cladistic analyses place Pteronarctos as sister to pinnipeds, in the clade Pinnipediformes.^[1]^[2]^[3]^[4]^[5]
