博罗金诺之战 (俄语：Бородинская битва， 法语：Bataille de la Moskowa) (1812年9月7日) 是所有拿破仑战争中最大和最血腥的单日战斗，超过二十五万士兵投进了战场，造成至少七万人死伤。由法皇拿破仑一世所领导的法军对阵俄罗斯帝国的米哈伊尔·库图佐夫元帅率领的俄军。

战斗发生在莫扎伊斯克镇以西的博罗金诺村附近。法军虽然夺取了各个重要据点，俄军也因战略考量和差劣的军队素质被迫撤退，战果却没有让拿破仑有半点高兴。这次战斗是拿破仑在俄罗斯境内的最后一次攻势，是侵俄战役中的转捩点。

The Battle of Borodino (Russian:Бородинское сражение, Borodinskoe srazhenie; French:Bataille de la Moskova), fought on September 7, 1812, was a battle fought in the Napoleonic Wars during the French invasion of Russia. The fighting involved around 250,000 troops and left at least 70,000 casualties, making Borodino the deadliest day of the Napoleonic Wars. Napoleon's Grande Armée launched an attack against the Russian army, driving it back from its initial positions but failing to gain a decisive victory. Both armies were exhausted after the battle and the Russians withdrew from the field the following day. Borodino was the last Russian effort at stopping the French advance on Moscow, which fell a week later; because the Russian army was not decisively defeated, the French had no clear way of bringing Czar Alexander to capitulate, resulting in the retreat from Moscow and the defeat of the French invasion.
