William Graham Sumner (October 30, 1840 – April 12, 1910) was an American clergyman, social scientist, and neoclassical liberal. He taught social sciences at Yale University, where he held the nation's first professorship in sociology and became one of the most influential teachers at any other major school.

Sumner wrote extensively on the social sciences, penning numerous books and essays on ethics, American history, economic history, political theory, sociology, and anthropology. He supported laissez-faire economics, free markets, and the gold standard, in addition to coining the term "ethnocentrism" to identify the roots of imperialism, which he strongly opposed. As a spokesman against elitism, he was in favor of the "forgotten man" of the middle class—a term he coined. He had a prolonged influence on American conservatism.
