Gérard Laumon (French: [lomɔ̃]; born 1952) is a French mathematician working in number theory and the Langlands program.

Laumon studied at the École Normale Supérieure and Paris-Sud 11 University, Orsay.^[1]

In 1987, Vladimir Drinfeld and Laumon formulated the geometric Langlands conjecture for general linear groups ${\displaystyle GL(n,K)}$ over a function field ${\displaystyle K}$.^{[2]: 46 [3]}

In 2008, Laumon and Ngô Bảo Châu proved the fundamental lemma for unitary groups, a component in the Langlands program in number theory.^[4][5]

He was awarded the Silver Medal of the CNRS in 1987, the E. Dechelle prize of the French Academy of the Sciences in 1992, and the Clay Research Award in 2004.^[4] Laumon and Ngô received the Clay Research Award for the proof of the fundamental lemma for unitary groups, a component in the Langlands program in number theory, in 2004.^[4]

In 2012, he became a fellow of the American Mathematical Society.^[6]
