Operation Bagration (Russian: Oперация Багратион, Operatsiya Bagration) was the codename for the Soviet 1944 Belorussian Strategic Offensive Operation during World War II, which cleared German forces from the Belorussian SSR and eastern Poland between 22 June and 19 August 1944.

The operation was named after 18th–19th century Georgian Prince Pyotr Bagration, general of the Imperial Russian Army who received a mortal wound at the Battle of Borodino. The Soviet armies directly involved in Operation Bagration were the 1st Baltic Front under Army General Hovhannes Bagramyan, the 1st Belorussian Front commanded by Army General Konstantin Rokossovsky, who was promoted to Marshal on 29 June 1944, the 2nd Belorussian Front commanded by Colonel-General G. F. Zakharov, and the 3rd Belorussian Front commanded by Colonel-General Ivan Chernyakhovsky. The operation resulted in the almost complete destruction of the German Army Group Centre and three of its component armies: the Fourth Army, Third Panzer Army and Ninth Army. It "was the most calamitous defeat of all the German armed forces in World War II". By the end of the operation most of the western Soviet Union had been reconquered and the Red Army had achieved footholds in Romania and Poland.
