John Bellamy Foster (born August 19, 1953) is an American professor of sociology at the University of Oregon and editor of the Monthly Review.

He submitted his 1979 paper, The United States and Monopoly Capital: The Issue of Excess Capacity, to Paul Sweezy of Monthly Review.

Along with Robert McChesney, who had since their days at Evergreen College become a leading scholar of the political economy of the media, Foster joined Paul Sweezy and Harry Magdoff as a co-editor of Monthly Review in 2000.

[11] As editor of Monthly Review, Foster returned to his earlier work on the political economy of capitalism, but with a renewed focus on the role of U.S. foreign policy following September 2001.

His 2006 book Naked Imperialism, along with frequent editorials in the pages of Monthly Review, attempted to account for the growing U.S. military role in the world and the shift toward a more visible, aggressive global projection.

[13][14] Critique of Intelligent Design, Foster’s book co-authored with Brett Clark and Richard York, is a continuation of his research on materialist philosophy and the relationship between ancient Greek philosopher Epicurus and Karl Marx.

In the book, "Foster explores how socialist analysts and materialist scientists of various stamps, first in Britain, then the United States, from William Morris and Friedrich Engels to Joseph Needham, Rachel Carson, and Stephen Jay Gould, sought to develop a dialectical naturalism, rooted in a critique of capitalism.
