Grodno Sejm (; ; ) was the last Sejm (session of parliament) of the Polish-Lithuanian Commonwealth. The Grodno Sejm, held in fall of 1793 in Grodno, Grand Duchy of Lithuania (now Hrodna, Belarus) 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.
