Probably Kursk, in the summer of 1943. The Soviets had complete intelligence of German attack plans, and prepared defenses in depth, up to fifty miles in depth actually. After absorbing the German attack the Russians went over to the counter-offensive, and never stopped rolling until they reached Berlin. The Germans never again had the strength to mount another massive offensive, or regain the initiative.
But your question would also describe Moscow, in December, 1941. The Germans had reached the outskirts of Moscow, could hear the clock bells downtown. After learning from spies that the Japanese had no plans to attack in the east while the Germans savaged them in the west, the Soviets moved hundreds of thousands of troops from the east and counterattacked, and the Germans were never again anywhere near Moscow. Losing Moscow might have been the end for the Russians.
If you're asking for school your teacher might be wanting Stalingrad, but that was more an epic defense by the Soviets, not a true counter-offensive.
It sounds as if you are thinking of the Battle of Stalingrad.

It is a common name used for the Ardennes Offensive or as the Germans called it, Operation Watch on the Rhine which was a German Counter-attack through the Ardennes toward the Port of Antwerp. It was the biggest US battle of WWII. It is a common name for the battle because of the massive bulge in Allied lines.
Massive Allied armies landed in France and started pushing the German occupiers back.
This type of warfare was known as Blitzkrieg -- German for 'lightning war'.
In 1940, the German army and air force overwhelmed France and the lowlands with massive surprise attacks on Allied defenses. Defensive walls such as the Marginot Line, were simply outflanked by the massive assaults by German tanks and armies. This was a "lightening war " of in Germ a Blitzkrieg that quickly conquered Western Europe within months. Soon Hitler was in Paris itself and forced France to surrender.
By January 1943, the Soviets already launched their counter offence and as a result, the German flanks began to weaken. After this the soviets launched a final counter offence (Operation Little Saturn) and this was a res ponce to the German offence known as Operation Winter Storm. During January, the soviets were in the 2nd stage of Operation Little Saturn and during this month, the Soviets destroyed the Hungarian 2nd Army and nearly encircles the German 2nd Army. On January 13th 1943, whilst the Soviets destroyed the Hungarian 2nd Army, they also attack the Italian 8th army Alpine corp and this corp was unaffected prior to January 1943. Once the soviets were able to advance 200 KM, they encircled the Italian Alpine Corps. This was similar to what happened to the German 6th Army but unlike the German 6th Army, the Alpine corps fought their way out and on January 17th,the launched a full retreat.

Because Germany diminished all of its resources fighting, and when it planned it's final attack Paris, Russia moved quickly and attacked its colonies, quickly intercepting them, and Japan took control of the German spheres of influence in China. With Germany out of resources and outmatched, the allies (France, Brittain, Russia) launched a massive counter attack, and the germans were forced to ask for an Armstice.
Operation Barbarossa was the German code name for their attack into Russia, which was launched on Sunday 22 June 1941.
