Anaxyrus, containing the North American toads, is a genus of true toads in the family Bufonidae.

Most species in this genus were initially classified in Bufo, but were split due to their genetic divergence and geographic separation.

Some authorities still consider Anaxyrus to be a subgenus within Bufo.

[2][3] However, other authorities have disputed this classification, as doing so would also require all morphologically distinct Old World toad species to also be placed in Bufo.

[1] The following fossil taxa are also known, all of which were also previously placed in Bufo:[4]
