North American porcupines, Erethizon dorsatum, have the northern most range of all porcupines. They inhabit much of North America between the Arctic Ocean and northern Mexico. Porcupines are found throughout most of Alaska and Canada, in the northern part of the Great Lakes region, all throughout the west and northeast regions of the United States. Populations have been studied extensively in the eastern deciduous forests of New York and Massachusetts, the Great Basin Desert, and the woodlands of Texas.
