Count Stanisław Małachowski, of the Nałęcz coat-of-arms (Polish pronunciation: [staˈɲiswaf mawaˈxɔfskʲi]; 1736–1809) was a Polish statesman, the first Prime Minister of Poland, a member of the Polish government's Permanent Council (Rada Nieustająca) (1776–1780), Marshal of the Crown Courts of Justice from 1774, Crown Grand Referendary (1780–1792) and Marshal of the Four-Year Sejm (1788–1792).

The son of Jan Małachowski, the royal grand chancellor, Małachowski was named marshal (speaker) of the Sejm (Diet) in 1788. He was the prime force behind the constitution, adopted in 1791, that embodied such modern western European reforms as majority rule in parliament, separation of powers, and enfranchisement of the middle classes; this constitution was abrogated at the Second Partition of Poland in 1792. In 1807–09 Małachowski served as president of the senate (government) of the Duchy of Warsaw, promoted by Napoleon Bonaparte.
