Charles Legardeur de Tilly (1616 – November 10, 1695) was a merchant, fur trader, seigneur and official in New France.
He married Geneviève, the daughter of Jean Juchereau de Maur, in 1648.
In partnership with François Byssot de la Rivière and Jean-Paul Godefroy, Tilly hunted seals at Tadoussac and traded in beaver pelts.
In the fall of 1650, he returned to France to acquire the fishing monopoly at Tadoussac from the Company of One Hundred Associates.
Tilly subsequently submitted to Frontenac and returned to the Council, serving until 1688, when his son Pierre-Noël became a member.
