Ofer Gabber (עופר גאבר; born May 16, 1958) is a mathematician working in algebraic geometry.

In 1978 Gabber received a Ph.D. from Harvard University for the thesis Some theorems on Azumaya algebras, written under the supervision of Barry Mazur.^[1] Gabber has been at the Institut des Hautes Études Scientifiques in Bures-sur-Yvette in Paris since 1984 as a CNRS senior researcher. He won the Erdős Prize in 1981 and the Prix Thérèse Gautier from the French Academy of Sciences in 2011. In 1981 Gabber with Victor Kac published a proof of a conjecture stated by Kac in 1968.^[2]
