Seweryn Rzewuski (Polish pronunciation: [sɛˈvɛrɨn ʐɛˈvuskʲi]; 13 March 1743 in Podhorce – 11 December 1811 in Vienna) was a Polish nobleman, writer, poet, general of the Royal Army, Field Hetman of the Crown, Voivode of Podolian Voivodeship and one of the leaders of the Targowica Confederation.

As voivode, he signed the election of Stanisław II Augustus in 1764,[1] and was later an envoy to the Repnin Sejm.

On 4 September 1775, both received in restitution from the king the Orders of St. Stanislaus and the White Eagle, but this was not enough to reconcile Seweryn, who blamed Poniatowski for his ordeal.

He was an envoy at the Four-Year Sejm,[3] at which he was one of the leaders of the Hetmans' Party, opposing all reforms.

During the Kościuszko Uprising he was sentenced to death and the confiscation of belongings in absentia by the Supreme Criminal Court and executed in effigy on 29 September 1794.
