Lepidodactylus zweifeli is a species of gecko. It is endemic to New Guinea and only known from the Adelbert Mountains in Madang Province, Papua New Guinea. It is named for Richard G. Zweifel, an American herpetologist.
Lepidodactylus zweifeli is known from two male specimens collected at 670m (2,200feet) above sea level from what is presumed to have been hill forest. They measure NaN1NaN1 in snout–vent length.
