Robert V. Kohn (born in 1953) is an American mathematician working on partial differential equations, calculus of variations, mathematical materials science, and mathematical finance. He is a professor at the Courant Institute of Mathematical Sciences, New York University.

Kohn studied mathematics at Harvard University, obtaining his bachelor's degree in 1974. He obtained his Ph.D. at Princeton University in 1979, as a student of Frederick Almgren.

Kohn is best known for his works on non-linear partial differential equations, specially the ones with Louis Nirenberg and Luis Caffarelli, where they obtained partial results about the regularity of weak solutions of the Navier–Stokes equations.

He received a Sloan Research Fellowship in 1984. In 2006, he was a plenary speaker at the International Congress of Mathematicians, in Madrid (Energy driven pattern formation). He is a fellow of the American Mathematical Society.
