Thomas Foot (fl. 1790 - 1825) was a British map engraver active in London around the turn of the 18th century. Foot apprenticed to Garnet Terry of the Tinplate Workers. He was the son of William Foot, a stable keeper based on Chapel Street, Grosvenor Square, London. Foot engraved extensively for the Ordnance Survey from about 1801 to 1804, when he was imprisoned for debt. In addition to his work with the Ordnance Survey, Foot also engraved for Robert Wilkinson, William Faden, Aaron Arrowsmith, James Colnett, and many others.
