Lieutenant General Sir John Gaspard Le Marchant GCMG KCB (1803–1874) was a British Army officer and governor of Newfoundland from 1847 to 1852. He was criticized for misappropriation of relief funds collected for the 1846 fire victims of the June 1846 fire that devastated most of St. John's. He later became the Lieutenant Governor of Nova Scotia (1852–1858).

Le Marchant was the son of Major-General John Le Marchant and the younger brother of Sir Denis Le Marchant, 1st Baronet, and was educated at High Wycombe Royal Grammar School and the Royal Military College, Sandhurst.

In 1820, at the age of seventeen, he was commissioned into the 10th Foot as an Ensign. In 1821 he transferred to the 57th Foot as a Lieutenant and later transferred to the 98th Foot, in which he was promoted Major. In 1835 he became adjutant-general of the British Auxiliary Legion in Spain with the rank of Brigadier-General. He transferred to the 20th Foot in 1837, the 99th Foot as Lieutenant-Colonel in 1839, the 85th Foot in 1845, and the 11th Foot as Colonel in 1862, holding the latter post until his death.
