The Patriotic Party, also known as the Patriot Party or, in English, as the Reform Party, was a political movement in the Polish–Lithuanian Commonwealth in the period of the Four-Year Sejm of 1788–1792, whose chief achievement was the Constitution of 3 May 1791. The reformers aimed to strengthen the ailing political machinery of the Commonwealth, to bolster its military, and to reduce foreign political influence, particularly that of the Russian Empire. It has been called the first Polish political party, though it had no formal organizational structure. The Party was inspired by the ideals of the French Revolution, and its name, proudly used by themselves, was a tribute to the Dutch Patriots.

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.
