Lieutenant General Sir John Gaspard Le Marchant GCMG KCB (1803–1874) was a British Army officer and governor of Newfoundland from 1847 to 1852.

In 1835 he became adjutant-general of the British Auxiliary Legion in Spain with the rank of brigadier-general.

[2] Le Marchant was opposed to the idea of responsible government and condemned local merchants of amassing wealth in the Colony and then returning to England.

After the fire of 1846 funds were collected for the victims and Le Marchant, acting upon Robert Law's recommendation that no further money be given to victims, then directed funds to the repair of public buildings and construction of roads in St. John's and the outports.

While in Malta, he had some portrait photos taken of him and his daughters by Maltese photography pioneer Leandro Preziosi.
