Operation Mars was the operation codename for the Rzhev offensive operation part of the Rzhev-Vyazma strategic offensive operation launched by Soviet forces against German forces during World War II. It took place between 25 November-20 December, 1942 in a salient in the vicinity of Moscow.

Orchestrated and led by Marshal Zhukov, and launched in tandem with Operation Uranus, the successful counteroffensive at Stalingrad, Mars proved to be a monumental setback. Designed to dislodge the German Army from its position west of Moscow, Mars cost the Soviets an estimated 335,000 dead, missing and wounded men and over 1,600 tanks. Fought in bad weather and on impossible terrain the offensive faltered despite an initial success in some sectors. The manner in which Operation Mars was fought and the carnage the operation produced has few parallels in the later war years. For grisly results, its closest peer would turn out to be another of Zhukov's operations: the frontal assault on the Seelow Heights during April 1945.
