Jakub Jasiński of Rawicz Clan (born 24 July 1761 in Węglów near Pyzdry in Greater Poland - 4 November 1794 in Warsaw, Poland) was a Polish general, and poet of Enlightenment. He participated in the War in Defence of the Constitution in 1792, was an enemy of the Targowica Confederation and organized an action against its supporters in Wilno. He was killed in the Battle of Praga in 1794.

A graduate of the Warsaw-based Szkoła Rycerska, with time he became the tutor of engineering at his alma mater. He fought with distinction in the War in Defense of the Constitution of 1792. After the king joined the Targowica Confederation he remained loyal to the new authorities. In 1789 he became the commanding officer of the Engineering Corps for Lithuania.

The war of liberation

During the Kościuszko Uprising of 1794 Jasiński was among the most prominent members of the radical wing of the Polish Jacobites and at the same time a successful military commander of partisan forces in the area of the Grand Duchy of Lithuania. In April of that year he liberated the city of Wilno by leading a successful uprising there. Supported by Tadeusz Kościuszko and appointed the commander in chief of all the partisan forces in the former Grand Duchy, he managed to defeat numerous Russian garrisons in the area. However, accusations of radical republicanism brought him into conflict with the state authorities, and by the beginning of June he was forced to resign as commander-in-chief of Lithuanian forces and pass his office to General Michał Wielhorski. Jakub Jasiński continued to harass enemy forces in Lithuania and then withdrew with a small partisan troop towards Warsaw. There he perished in November during the defense of Warsaw against the forces of Alexander Suvorov.

Among his literary works are numerous poems of satirical and fabled character, under huge influence of Voltaire, for example Jasiński's better-known "Sprzeczki" (Quarrels). He was also an author of many patriotic and revolutionary poems and songs against injustices, inspired by the French Revolution, and arousing hope of a similar one in his homeland.
