Charles Jacques Huault de Montmagny (French pronunciation: [ʃaʁl də mɔ̃maɲi]; c. 1583 to 1599 – 4 July 1657) was governor of New France from 1636 to 1648.

Born in Montmagny, Val-d'Oise, to Charles Huault (descended from a noble family headed by Jacques Huault, a counsellor under Henri II of France 1534 to 1580[1]) and Antoinette Du Drac, Huault de Montmagny was educated by the Jesuits in Malta under the Order of the Knights Hospitaller in 1622.

His name 'Montmagny' roughly translated into the Iroquoian languages as "Onontio" (Great Mountain), a title which the Iroquois Confederacy used for all subsequent Governors of Quebec.

He became the inspiration of the character Montmagny by Cyrano de Bergerac in his novel L'autre Monde.
