Wild horses roam several areas of North America, as well as the rest of the world. In North America, areas such as Chincoteague Island and Assateague Island have herds of feral horses according to Paw Nation.
Feral horses can be found in all areas of the United States, as well as in international areas such as Portugal and Australia. According to Return to Freedom, most wild horses live on public land that is managed by agencies such as Bureau of Land Management and the Fish and Wildlife Service. Feral horses are considered descendants of domesticated horses and are simply horses that have not been tamed.
