Tyler Cowen (born January 21, 1962) occupies the Holbert C. Harris Chair of economics as a professor at George Mason University and is co-author, with Alex Tabarrok, of the popular economics blog Marginal Revolution. He currently writes the "Economic Scene" column for the New York Times and writes for such magazines as The New Republic and The Wilson Quarterly.

Cowen's primary research interest is the economics of culture. He has written books on fame (What Price Fame?), art (In Praise of Commercial Culture), and cultural trade (Creative Destruction: How Globalization is Changing the World's Cultures). In Markets and Cultural Voices, he relays how globalization is changing the world of three Mexican amate painters. Cowen argues that free markets change culture for the better, allowing them to evolve into something more people want. Other books include Public Goods and Market Failures, The Theory of Market Failure, Explorations in the New Monetary Economics, Risk and Business Cycles, Economic Welfare, and New Theories of Market Failure.
