John Heriot (22 April 1760 – 2 August 1833) was a Scottish journalist and writer. He was forced to join the Royal Marines due to family hardship, and served as a junior officer during the American Revolutionary War. He was wounded in 1780 at the Battle of Martinique, and retired from the service in 1783; after living in financial difficulties for some years, he published two moderately successful novels in the 1780s, the second of which drew extensively on his experiences as a half-pay officer.
