Archibald Cameron of Lochiel was a Scottish physician and prominent leader in the Jacobite rising of 1745. He was the personal physician of Charles Edward Stuart, and younger brother of Donald Cameron of Lochiel, otherwise known as the Gentle Lochiel, who led Clan Cameron during the rising. In 1753 at Tyburn, he was executed for high treason, being the last Jacobite to be executed. In popular memory, he is sometimes referred to as Doctor Archie.

The Jacobite rising of 1745 was an attempt by Charles Edward Stuart to regain the British throne for his father, James Francis Edward Stuart. It took place during the War of the Austrian Succession, when the bulk of the British Army was fighting in mainland Europe, and proved to be the last in a series of revolts that began in March 1689, with major outbreaks in 1715 and 1719.
