Xiao-Gang Wen (simplified Chinese: 文小刚; traditional Chinese: 文小剛; pinyin: Wen2 Xiao3 Gang1) (born November 26, 1961) is a Chinese-born American physicist. He is a Cecil and Ida Green Professor of Physics at the Massachusetts Institute of Technology. His expertise is in condensed matter theory in strongly correlated electronic systems.

He is the author of a well-known book in advanced quantum many-body theory entitled, Quantum Field Theory of Many-body Systems: From the Origin of Sound to an Origin of Light and Electrons (Oxford University Press, 2004)

Wen studied superstring theory under theoretical physicist Edward Witten at Princeton University where he received his Ph.D. degree in 1987. He later switched his research field to condensed matter physics while working with theoretical physicists Robert Schrieffer, Frank Wilczek, Anthony Zee in Institute for Theoretical Physics, UC Santa Barbara (1987-1989).
