The amphibian fauna of the Świętokrzyski National Park consists of 14 species. Among them, there are 3 newts: Great Crested Newt, Smooth Newt, also known as Common Newt, and Alpine Newt. The last species is the most characteristic one since, besides the Świętokrzyskie mountains, it occurs in Poland only in the Carpathians and the Sudets. The population of the Alpine Newt in the Świętokrzyskie mountains prove that they are to be counted as true mountains despite being one of the lowest in Europe.

Tailless amphibians include the following toads: European Fire-bellied, Common Spadefoot, Common, Green, Natterjack; and frogs: Tree, Pool, Edible, Marsh, Common, Moor.
