His father was Hetman Wacław Rzewuski, while his mother was Anna Lubomirska. He had nine siblings. He firstly studied in Warsaw. Starting from 1754, Rzewuski's educator was L. A. Caraccioli, and under his care, all of the children in the family were educated abroad (Rzewuski visited, most notably, Austria, Italy and France).

As voivode, he signed the election of Stanisław II Augustus in 1764, and was later an envoy to the Repnin Sejm. Because of his opposition to the Russian ambassador there, he and his father, Wacław Rzewuski were kidnapped on the night of 13/14 October 1767 by Russian forces under the command of General Iosif Igelström and imprisoned in Kaluga. He returned to Poland in 1773. 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, at which he was one of the leaders of the Hetmans' Party, opposing all reforms. He was especially against any changes to the power of the hetmen, having been one since 1774. He was later stripped of this rank by the Sejm for not answering the letters of the Military Commission. In 1791 he went to Russia, where he helped Catherine II with her pretense of only interfering with the affairs of the Polish–Lithuanian Commonwealth after being pleaded with to help by their citizens. He was one of the founding leaders of the Targowica Confederation, having previously been involved in the Radom Confederation in 1767. In 1793, after Russian and Prussian plans for the Second Partition of Poland became known, he moved to the Galicia and Lodomeria, the land taken from the Commonwealth by Austria in the First Partition of Poland and gave up politics. 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. He was married to Konstancja Małgorzata Lubomirska and had three children, Wacław Rzewuski, Izabella Rzewuska and Maria Rzewuska.
