Bernard Malgrange (born 6 July 1928) is a French mathematician who works on differential equations and singularity theory. He proved the Ehrenpreis–Malgrange theorem and the Malgrange preparation theorem, essential for the classification theorem of the elementary catastrophes of René Thom. He received his Ph.D. from Université Henri Poincaré (Nancy 1) in 1955.
