The meadow vole (Microtus pennsylvanicus), sometimes called the field mouse or meadow mouse, is a North American vole found across Canada, Alaska and the northern United States. Its range extends farther south along the Atlantic coast. One subspecies, the Florida salt marsh vole (M. p. dukecampbelli), is found in Florida, and is classified as endangered. Previously it was also found in Chihuahua, Mexico, but has not been recorded since 1998.
