The American toad is a common species of toad found throughout the eastern United States and Canada. It is divided into three subspecies—the eastern American toad , the dwarf American toad , and the rare Hudson Bay toad . A new taxonomy places this species in the genus ''Anaxyrus'' instead of ''Bufo''.
Races tend to hybridize with ''Anaxyrus woodhousii'' in their overlapping ranges.
