Lieutenant-General Robert Monckton (24 June 1726 – 21 May 1782) was a British Army officer, politician and colonial administrator. He had a distinguished military and political career, being second in command to General James Wolfe at the Battle of the Plains of Abraham and later being named the governor of New York. Monckton is also remembered for his role in a number of other important events in the French and Indian War, most notably the capture of Fort Beauséjour in Acadia, and the island of Martinique in the West Indies, as well as for his role in the expulsion of the Acadians from Nova Scotia and Acadia.
Monckton sat in the House of Commons of Great Britain between 1774 and 1782. Although never legally married, he had three sons and a daughter. The city of Moncton, New Brunswick (about 50 kilometres (31 mi) west of Fort Beauséjour) and Fort Monckton in Port Elgin, New Brunswick are named for him. A second more important Fort Monckton in Gosport, England is also named for him. It remains an active military establishment, and currently houses the training section of MI6.
