As of June 2026, the International Union for Conservation of Nature (IUCN) lists 432 critically endangered reptile species, including 50 which are tagged as possibly extinct.[1] 4.2% of all evaluated reptile species are listed as critically endangered; 15 subspecies, and 11 subpopulations are also listed as critically endangered.[2]

Additionally, 1,502 reptile species (14.5% of those evaluated) are listed as data deficient, meaning there is not sufficient information for a full assessment of conservation status.[2] As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN.[3] 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".[4]

This is a complete list of critically endangered reptile species and subspecies evaluated by the IUCN. Species considered possibly extinct by the IUCN are marked as such. Species and subspecies which have critically endangered subpopulations (or stocks) are indicated.
