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

As of September 2016, the International Union for Conservation of Nature (IUCN) lists 848 endangered amphibian species.[1] 13% of all evaluated amphibian species are listed as endangered. No subpopulations of amphibians have been evaluated by the IUCN.

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 exintction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered amphibians are listed separately. There are 1393 amphibian species which are endangered or critically endangered.

Additionally 1567 amphibian species (24% 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]
