Edward Hastings Chamberlin was an American economist. He was born in La Conner, Washington, and died in Cambridge, Massachusetts.

For most of his career Edward Chamberlin taught economics at Harvard (1937–1967). He coined the term “product differentiation” to describe how a supplier may be able to charge a greater amount for a product than perfect competition would allow. His most significant contribution was the Chamberlinian monopolistic competition theory. Chamberlin published his book The Theory of Monopolistic Competition in 1933, the same year that Joan Robinson published her book on the same topic: The Economics of Imperfect Competition.
