Eleutherodactylus lamprotes is a species of frog in the family Eleutherodactylidae endemic to the Massif de la Hotte, Haiti. Its common name is Castillon robber frog. The specific name refers to its contrasting colour patterns.
Males measure 20–37 mm (0.79–1.46 in) in snout–vent length. Dorsum is patternless brown to tan, whereas concealed surfaces of thighs, underside of hindlimbs, and axillae are bright orange. Vocal sac dark is brown, and venter is dark brown with large white spots. Dorsum is weakly tuberculate, but upper eyelids and upper surface of head have prominent, almost spine-like tubercles.
