The Russian Partition, sometimes called Russian Poland, constituted the former territories of the Polish–Lithuanian Commonwealth that were annexed by the Russian Empire in the course of late-18th-century Partitions of Poland. The Russian acquisition encompassed the largest share of Poland's population, living on 463,200 km2 of land constituting the eastern and central territory of the former commonwealth. The three partitions, which took place in 1772, 1793 and 1795, resulted in the complete loss of Poland's sovereignty, with its territory split between Russia, Prussia and Austria. The Napoleonic Wars saw significant parts of Prussia's and Austria's partitions reconstituted as the Duchy of Warsaw, most of which was then reconstituted as the Kingdom of Poland within the Russian Empire in 1815.

The 1793 Second Partition of Poland was the second of three partitions that ended the existence of the Polish–Lithuanian Commonwealth by 1795. The second partition occurred in the aftermath of the Polish–Russian War of 1792 and the Targowica Confederation of 1792, and was approved by its territorial beneficiaries, the Russian Empire and the Kingdom of Prussia. The division was ratified by the coerced Polish parliament (Sejm) in 1793 in a short-lived attempt to prevent the inevitable complete annexation of Poland, the Third Partition.
