The Château Frontenac is a grand hotel in Quebec City, Quebec, Canada, which is currently operated as Fairmont Le Château Frontenac. It was designated a National Historic Site of Canada in 1980. Prior to the building of the hotel, the site was occupied by the Chateau Haldimand, residence of the British colonial governors of Lower Canada and Quebec. The Château Frontenac was named after Louis de Buade, Count of Frontenac, who was governor of the colony of New France.

Although several of Quebec City’s buildings are taller, the landmark hotel is perched atop a tall cape overlooking the Saint Lawrence River, affording a spectacular view for several kilometers. The building is the most prominent feature of the Quebec City skyline as seen from across the St. Lawrence.
