This is a list of amphibians and reptiles found on the islands of Saint Kitts and Nevis, a two-island nation in the Caribbean Lesser Antilles.
The islands are separated by a narrow strait that is only 3.2 km wide and 15 m deep, and thus the two islands have very similar faunas.
There are two species of amphibian recorded on Saint Kitts and Nevis.
Including marine turtles and introduced species, there are 14 reptile species reported on Saint Kitts and 12 species on Nevis.
Note: All records of species that listed above are supported by Malhotra & Thorpe 1999, unless otherwise cited.
