Luc de la Corne, (1711 – October 1, 1784) also known as Saint Luc, is the son of Jean-Louis de La Corne de Chaptes (1666-1732), King's Lieutenant at Montreal, and Marie Pécaudy de Contrecœur.

Saint-Luc is an officer in the Compagnies Franches de la Marine; his brother Louis de la Corne, Chevalier de la Corne, later becomes a very successful merchant at Montreal.

Though relatively unknown, he plays a major role in American and Canadian history.

He is most famous for returning from the shipwreck of the Auguste off the coast of Cape Breton, Nova Scotia, at the age of fifty, during the dead of winter, to Quebec City—a trek of seventeen hundred miles.

He has a varied and courageous military career which earns him the cross of Saint Louis in 1759.

He fights at both the Battle of Fort William Henry during the French and Indian War and at the Battle of Saratoga during the American Revolution.

He becomes a very successful merchant and is heavily involved in the Montreal end of the fur trade.

His brother, Jean-Louis, is heavily involved in the fur trade and exploration and Luc controls the eastern end of his activities.

Another brother, François-Josué de La Corne is the commandant of Fort Kaministiquia for a time and large fur trade profits are realized

He is in partnership with Louis-Joseph Gaultier de La Vérendrye for three years south of Lake Superior

In the same period his brother, Louis de la Corne is commandant of the western forts founded mainly by the elder La Vérendrye.

Most of his ventures make large profits and, at the time of his death, he is one of the richest men in Canada.
