Eleutherodactylus eunaster is a species of frog in the family Eleutherodactylidae endemic to the Massif de la Hotte, Haiti. Its natural habitat is mesic hardwood closed-canopy forest at elevations of 575–1,300 m (1,886–4,265 ft) asl. It is an arboreal species that is moderately common in suitable habitat. It is threatened by habitat loss primarily caused by logging for charcoaling and slash-and-burn agriculture. While the species occurs in the Pic Macaya National Park, there is no active management for conservation, and habitat loss continues also in the park.
