This is a list of the reptile species recorded on Christmas Island. At the time of human settlement in the late 19th century, the island had five native species of lizard and one native snake. However, additional species were introduced during the 20th century, resulting in dramatic declines in the island's native reptile populations. ^[1]

Lizards

Christmas Island had five native lizard species at the time of human settlement, although the Christmas Island forest skink (Emoia nativitatis) is now considered extinct, ^[2] and the blue-tailed skink (Cryptoblepharus egeriae) and Lister's gecko (Lepidodactylus listeri) are extinct in the wild. ^{[3] [4]} Three additional species were introduced during the 20th century. ^[1]
