Wei-Ming Ni (; born 23 December 1950) is a Taiwanese mathematician. He is a Presidential Chair Professor at the Chinese University of Hong Kong, Shenzhen and a professor emeritus at the University of Minnesota. He was previously the director of the Center for PDE at the East China Normal University.

Education and career Ni works in the field of elliptic and parabolic partial differential equations. He graduated from National Taiwan University with a B.S. in mathematics in 1972 and earned his Ph.D. in mathematics from New York University in 1979 under Louis Nirenberg.

Ni is an editor-in-chief of the Journal of Differential Equations, and was an ISI Highly Cited Researcher in 2002. As said by the journal Discrete and Continuous Dynamical Systems:
