The American toad (Bufo americanus) is a common species of toad found throughout the eastern United States and Canada. It is divided into three subspecies—the eastern American toad (B. a. americanus), the dwarf American toad (B. a. charlesmithi), and the rare Hudson Bay toad (B. a. copei). A new taxonomy considers this species Anaxyrus americanus.
