List of amphibians of Arkansas

The U.S. state of Arkansas is located in the central part of the country. This list is derived largely from the Herps of Arkansas website.^[1] Conservation status is derived from NatureServe and represents the species' status within the state rather than their worldwide status. In Arkansas, there are 25 species of frog and toad, and 32 species of newts and salamanders. Of these species, 18 are ranked as "secure", 6 are "apparently secure", 10 are "vulnerable", 11 are "imperiled", 7 are "critically imperiled", and 1 is "possibly extirpated"; 3 species are not assessed.

Some species are unconfirmed in Arkansas but may occur. Many of these species are separated from Arkansas by the Mississippi River, and may be common in the bordering regions of Mississippi and Tennessee. Other species may be hypothesized to occur in the state but are not confirmed. Some have gene flow and form species hybrids in the state with a more widespread species, but purebred members of one of the hybrid parent species are not confirmed.^[1]

• Rocky Mountain toad (Anaxyrus woodhousii woodhousii) - Gene flow between this species and A. fowleri has been recorded in southwest Arkansas, but no purebred members of this species have been found.
• Eastern cricket frog (Acris crepitans) - Widespread east of the Mississippi River, but not recorded west of it.^[1]
• Southern cricket frog (Acris gryllus) - Widespread east of the Mississippi River, but not recorded west of it.^[1]
• Upland chorus frog (Pseudacris feriarum) - Widespread east of the Mississippi River, but not recorded west of it; may occupy regions in the northeast.^[1]
• Catahoula spotted dusky salamander (Desmognathus catahoula) - Recently described species known from eastern Texas and northern Louisiana. Its range may extend into southern Arkansas.^[58]
• Southern two-lined salamander (Eurycea cirrigera) - Widespread east of the Mississippi River, but not recorded west of it.^[1]
• Three-lined salamander (Eurycea guttolineata) - Widespread east of the Mississippi River, but not recorded west of it.^[1]
• Long-tailed salamander (Eurycea longicauda) - Some gene flow with the dark-sided salamander (Eurycea melanopleura) around Randolph County is reportedly from this species, but this species has not been confirmed in Arkansas.^[1]
• Mississippi slimy salamander (Plethodon mississippi) - Widespread east of the Mississippi River and especially near Memphis but not recorded west of the Mississippi River.^[1]
• Western waterdog (Necturus beyeri) - Red River and Mississippi River populations of Necturus louisianensis may be this species.
