List of critically endangered amphibians
As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct. 9.2% of all evaluated amphibian species are listed as critically endangered. No subpopulations of amphibians have been evaluated by the IUCN. Additionally, 1193 amphibian species (16.4% 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.
