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.

Grodno Sejm was the last Sejm of the Polish–Lithuanian Commonwealth. The Grodno Sejm, held in autumn 1793 in Grodno, Grand Duchy of Lithuania is infamous because its deputies, bribed or coerced by the Russian Empire, passed the act of Second Partition of Poland. The Sejm started on 17 June and ended on 23 November 1793. It ratified the division of the country in a futile attempt to prevent its subsequent complete annexation two years later in the 1795 Third Partition of Poland.
