Template:IUCN reptile chart

Endangered (EN) species are considered to be facing a very high risk of extinction the wild.

In September 2016, the International Union for Conservation of Nature (IUCN) listed 382 endangered reptile species.[1] Of all evaluated reptile species, 7.4% are listed as endangered. The IUCN also lists nine reptile subspecies as endangered.

Of the subpopulations of reptiles evaluated by the IUCN, one species subpopulation has been assessed as endangered.

For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered reptiles are listed separately. There are 578 reptile species which are endangered or critically endangered.

Additionally 910 reptile species (18% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN.[2] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed".[3]

This is a complete list of endangered reptile species and subspecies evaluated by the IUCN. Species and subspecies which have endangered subpopulations (or stocks) are indicated.
