Zacharie Cloutier (c. 1590 – September 17, 1677) was a French carpenter who immigrated to New France in 1634 as part of the Percheron immigration from the former province of Perche, settling in Beauport and founding one of the foremost families of Quebec. Known as the "family peacemaker," Cloutier played a significant role in resolving disputes within his family. He married Xainte Dupont in 1616 and, along with his family, traveled from Perche to New France. Cloutier was one of the first Frenchmen recruited to settle the Beauport area near Quebec City, making a vital contribution to the colony's population. He worked on constructing Giffard's manor house and other colonial buildings, and later received a land grant in Château-Richer, Quebec. Zacharie Cloutier is the common ancestor of the Cloutiers of North America, with over 10,850 French-Canadian descendants. His notable descendants include the Cloutiers of North America, some with spelling variations. Despite limited information about his ancestors, Cloutier's surname, derived from the Latin word for "nail," reflects his ancestors' occupation of crafting and selling nails. In honor of his historical significance, a house originally built and lived in by Cloutier was reconstructed and named a provincial heritage site in 1972, and a monument was erected in Beauport in 1984
