Acrisinae is a subfamily of the tree frog family Hylidae. There are only two genera in this subfamily, Acris (cricket frogs) and Pseudacris (chorus frogs). They are native to most of the Nearctic realm, and are found as far north as the Great Slave Lake in Canada, all across the United States, and down Baja California and some parts of northern Mexico. One species, the pacific tree frog (Pseudacris regilla), has been introduced to several locations outside its range, and it is possible that other species may have been as well.
