**Michel Ledoux** (born 1958) is a French mathematician, specializing in probability theory. He is a professor at the University of Toulouse.

Ledoux received in 1985 his Ph.D. from the University of Strasbourg with thesis *Propriétés limites des variables aléatoires vectorielles* which was made under the supervision of Xavier Fernique.

He has done important research on the isoperimetric inequality in analysis and probability theory.

In 2010 he received the Servant Prize of the French Academy of Sciences. In 2014 he was an invited speaker at the International Congress of Mathematicians in Seoul and gave a talk *Heat flows, geometric and functional inequalities*.
