Fabrice Bethuel (born 7 June 1963) is a French mathematician. He holds a chair at Paris VI University.

Bethuel earned his doctorate at Paris-Sud 11 University in 1989, under supervision of Jean-Michel Coron. In 1998 Bethuel was an Invited Speaker of the International Congress of Mathematicians in Berlin. He won the 1999 Fermat Prize, jointly with Frédéric Hélein, for several important contributions to the theory of variational calculus. He also won the 2003 Mergier–Bourdeix Prize [fr] for his fundamental discoveries at the interface between analysis, topology, geometry, and physics.
