Hugo Stumberg Kołłątaj, also spelled Kołłątay, was a prominent Polish constitutional reformer and educationalist, and one of the most prominent figures of the Polish Enlightenment. He served as Deputy Chancellor of the Crown between 1791–92. He was a Roman Catholic priest, social and political activist, political thinker, historian, philosopher, and polymath.

The ideas of the Age of Enlightenment in Poland were developed later than in Western Europe, as the Polish bourgeoisie was weaker, and szlachta (nobility) culture (Sarmatism) together with the Polish–Lithuanian Commonwealth political system were in deep crisis. The period of Polish Enlightenment began in the 1730s–40s, peaked in the reign of Poland's king, Stanisław August Poniatowski, went into decline with the Third Partition of Poland (1795) – a national tragedy inspiring a short period of sentimental writing – and ended in 1822, replaced by Romanticism.
