The Voronezh Front (Russian: Воронежский Фронт) was a major formation of the Soviet Union's Red Army during the Second World War. The name indicated the primary geographical region in which the front first fought, based on the town of Voronezh on the Don River. The front was established at the end of June 1942 when tanks of the German Wehrmacht's 6th Army reached Voronezh during the early stages of Operation Blau.
