The Lublin–Brest Offensive (Russian: Люблин‐Брестская наступательная операция, romanized: Lyublin-Brestskaya nastupatel'naya operatsiya, 18 July – 2 August 1944) was a part of the Operation Bagration strategic offensive by the Soviet Red Army to clear the Nazi German forces from the regions of Eastern Poland and Western Belarus. The offensive was executed by the left (southern) wing of the 1st Belorussian Front and took place during July 1944; it was opposed by the German Army Group North Ukraine and Army Group Centre.
The operation was accompanied by several other offensives, particularly the Lvov–Sandomierz Offensive of the 1st Ukrainian Front in the south; both offensives launched weeks after the start of the successful Operation Bagration to the north which cleared German forces from most of Belarus.
