John Jeffreys Pratt, 1st Marquess Camden (1759 – 1840), known as The Earl Camden from 1794 to 1812, was a British politician. He served as Lord Lieutenant of Ireland between 1795 and 1798 and as Secretary of State for War and the Colonies between 1804 and 1805. Disliked in Ireland as an opponent of Roman Catholic emancipation and as the exponent of an unpopular policy, Camden's term of office was one of turbulence, culminating in the rebellion of 1798: his refusal to reprieve the United Irishman William Orr, convicted of treason on the word of one witness of dubious credit, aroused great public indignation.
