Lieutenant-Colonel Sir Duncan MacDougall (1787 – 10 December 1862) was a British Army officer who fought in the Peninsular War and War of 1812. He rose to command the 79th Regiment of Foot before serving as second-in-command of the British Auxiliary Legion during the First Carlist War.

MacDougall joined the British Army in 1804. After initial service at the Cape of Good Hope he fought through much of the Peninsular War in Spain and Portugal as a subaltern, being seriously wounded at the Battle of Salamanca. He became aide de camp to Major-General Robert Ross during the War of 1812, and was by his side at the Battle of Baltimore when the general was killed. Promoted to major, MacDougall became aide de camp to Major-General Sir Edward Pakenham. He was riding alongside Pakenham when the latter was mortally wounded at the Battle of New Orleans.

MacDougall was promoted to lieutenant-colonel in 1825. Sent to command colonial militia in Nova Scotia, he transferred to the 79th Regiment of Foot in 1830 and commanded it from 1832. In 1835 he joined the British Auxiliary Legion as second-in-command. He resigned a year later amidst disagreements over strategy with the commander of the Legion, De Lacy Evans. MacDougall left the British Army in 1838 and in retirement was a champion of militia and volunteer movements, establishing the Royal Lancashire Militia Artillery in 1853 and assisting with the formation of the Volunteer Force in 1859.
