Admiral Sir John Thomas Duckworth, 1st Baronet, GCB (9 February 1748 – 31 August 1817) was an English Royal Navy officer, colonial administrator and politician who served in the Seven Years' War, American War of Independence, French Revolutionary and Napoleonic Wars and War of 1812. In addition to serving as the governor of Newfoundland, he was also a member of the British House of Commons during his semi-retirement. Duckworth, a vicar's son, achieved much in a naval career that began at the age of 11.

Serving with most of the great names of the Royal Navy during the later 18th and early 19th centuries, he fought almost all of Britain's enemies on the seas at one time or another, including a Dardanelles operation that would be remembered a century later during the First World War. He was in command at the Battle of San Domingo, the last great fleet action of the Napoleonic Wars.
