Georges Mareschal (8 April 1658, Calais – 13 December 1736, Château de Bièvres) was a French surgeon. In 1707 he was ennobled, and was known as Georges Mareschal, seigneur de Bièvre.
He was the son of John Marshall, an Irish gentleman who was knighted in 1643 for his service during the Battle of Rocroi. In 1677 Mareschal moved to Paris, where he worked as a surgical assistant. From 1684 onward, he worked at the Hôpital de la Charité, where in 1688 he became master-surgeon, later earning the title of chief-surgeon (1692).
