Night Comes to the Cumberlands (1963) is a book by Harry Caudill that brought attention to poverty in Appalachia and is credited with making the Appalachian area a focus of the United States government's "war on poverty". In Poverty in the United States: An Encyclopedia of History, Politics, and Policy, the book is described as a "definitive text on poverty in Appalachia among journalists, academics, and government bureaucrats concerned with economic inequality in America."
