Harry W. Child (1857–1931) was an entrepreneur who managed development and ranching companies in southern Montana. He was most notable as a founder and longtime president of the Yellowstone Park Company, which provided accommodation and transportation to visitors to Yellowstone National Park from 1892 to 1980. Child was, with park superintendent and National Park Service administrator Horace Albright, singularly responsible for the development of the park as a tourist destination and for the construction of much of the park's visitor infrastructure.
