Field Marshal John Campbell, 5th Duke of Argyll (June 1723 – 24 May 1806), styled Marquess of Lorne from 1761 to 1770, was a Scottish soldier and nobleman. After serving as a junior officer in Flanders during the War of the Austrian Succession, he was given command of a regiment and was redeployed to Scotland where he opposed the Jacobites at Loch Fyne at an early stage of the Jacobite Rebellion and went on to fight against them at the Battle of Falkirk Muir and then at the Battle of Culloden. He later became adjutant-general in Ireland and spent some 20 years as a Member of Parliament before retiring to Inveraray Castle.
