Wen-Hsiung Li (Chinese: 李文雄; pinyin: Lǐ Wénxióng; born September 22, 1942) is a Taiwanese-American scientist working in the fields of molecular evolution, population genetics, and genomics. He is currently the James Watson Professor of Ecology and Evolution at the University of Chicago and a Principal Investigator at the Institute of Information Science and Genomics Research Center, Academia Sinica, Taiwan.

Li was born in 1942 in Taiwan. In 1968 he received a M.S. in geophysics from National Central University. In 1972 he received his Ph.D in applied mathematics at Brown University in Providence, Rhode Island. From 1972 to 1973 he was a post-doctoral researcher at the University of Wisconsin Madison (genetics), working with James F. Crow. In 1973 he moved to the University of Texas, where he was appointed as a professor in 1984. Since 1998 he has been a professor at The University of Chicago.

Li is best known for his studies on the molecular clock (i.e. rates and patterns of DNA sequence evolution^[8]) and on the patterns and consequences of gene duplication.^[9]

In 2003, he received the international Balzan Prize for his contribution to genetics and evolutionary biology, and was elected to the National Academy of Sciences, who cited his role in "establishing theoretical foundations for molecular phylogenetics and evolutionary genomics"[1]. He is the author of the first textbook in the field of molecular evolution, Molecular Evolution and Fundamentals of Molecular Evolution (co-authored with Dan Graur), and an author on more than 200 peer-reviewed publications.
