Wei-Ming Ni (; born 23 December 1950) is a Taiwanese mathematician at the University of Minnesota and the Chinese University of Hong Kong, and the former director of the Center for PDE at the East China Normal University. He works in the field of elliptic and parabolic partial differential equations. He did undergraduate work at National Taiwan University and obtained his Ph.D. at New York University, in 1979, under the supervision of Louis Nirenberg. He is an editor-in-chief of the Journal of Differential Equations, and was an ISI Highly Cited Researcher in 2002.
