Edward W Ng (Chinese: 伍煒國; September 23, 1939 – December 14, 2018) was an American applied mathematician who had also held the positions of senior scientist, senior engineer and technical manager in the U.S. Space Program. He is noted for his broad variety of mathematical applications in space science and engineering. He has also contributed conscientiously in the spin-off of technology from the space program, with applications in such diverse subjects as Bose–Einstein distribution in mathematical physics, symbolic and algebraic computation, computational physics and biomedical research.

Ng attended the Queen Elizabeth School, Hong Kong for secondary education, and the University of Minnesota for his bachelor's degree. He received his M.A. and PhD degrees from Columbia University. He was employed at the Jet Propulsion Laboratory (JPL) of the California Institute of Technology, aka Caltech under contract with the National Aeronautics and Space Administration (NASA). He retired in 2006.

Ng was elected a Fellow of the American Association for the Advancement of Science (AAAS) and is cited in the American Men and Women of Science.^[1] He was the editor of "Symbolic and Algebraic Computation" (ISBN 3-540-09519-5),^[2] in the Springer Science Lecture Notes Series. He was also a co-editor of the Proceedings of a NATO Advanced Study Institute in applied mathematics (ISBN 978-90-277-1571-5).^[3] He has published numerous technical papers of diverse mathematical applications in space sciences and engineering (selected list in external link below). His papers have appeared in Astrophysical Journal, Mathematics of Computation, Celestial Mechanics and Dynamical Astronomy,^[4] Journal of Computational Physics, M.I.T. Journal of Mathematics and Physics,^[5] ACM Transactions on Mathematical Software and Proceedings of the American Institute of Aeronautics and Astronautics.
