The First Pitt Ministry was the term of office from 1783-1801 during which William Pitt the Younger served as the last prime minister of Great Britain from 1783 until the Acts of Union 1800, and the first official prime minister of the United Kingdom from January 1801 until he left office in March 1801. He was also Chancellor of the Exchequer for all his time as prime minister. His 1783-1801 term is known as the First Pitt Ministry because he would serve again as Prime Minister from 1804 until his death in 1806. He is known as "Pitt the Younger" to distinguish him from his father, William Pitt the Elder, who had also previously served as prime minister from 1766-1768.

In 1800, the Acts of Union between Great Britain and Ireland were accepted by their respective parliaments, creating the new United Kingdom of Great Britain and Ireland (UK), which would be governed by the former Parliament of Great Britain (now the UK Parliament). Pitt governed this new state for the first month of its existence, until he resigned due to differences with King George III over Catholic emancipation, which Pitt had come to favor but the King vehemently opposed.
