The Château Ramezay is a museum and historic building on Notre-Dame Street in Old Montreal, opposite Montreal City Hall in Montreal, Quebec, Canada.
Built in 1705 as the residence of then-governor of Montreal, Claude de Ramezay, the Château was the first building proclaimed as a historical monument in Quebec and is the province's oldest private history museum. It was designated a National Historic Sites of Canada in 1949.
Over the years, the Château changed owners and functions several times, with Ramezay's descendants selling the manor to the fur-trading Compagnie des Indes.
