Operation Polkovodets Rumyantsev (Russian: Полководец Румянцев literally: "Regiment leader Rumyantsev", after 18th-century Field Marshal Peter Rumyantsev) was a code name for the Belgorod-Kharkov Strategic Offensive Operation conducted by the Red Army between 3 August 1943 and 23 August 1943 against the Wehrmacht's 4th Panzer Army and Army Group Kempf during World War II. The operation was conducted by the Voronezh and Steppe Fronts in the Belgorod (southern) sector of the Kursk Bulge. In one German source by Wilhelm Keitel this operation is referred to as the "Fourth Battle of Kharkov" although it is unrelated to the Third Battle of Kharkov.
