Château Vaudreuil was a stately residence and college in Montreal, Quebec, Canada. It was constructed between 1723 and 1726 for Philippe de Rigaud, Marquis de Vaudreuil, as his private residence by Gaspard-Joseph Chaussegros de Léry. Though the Château Saint-Louis in Quebec City remained the official residence of the Governors General of New France, the Château Vaudreuil was to remain as their official home in Montreal up until the British Conquest in 1763. In 1767, it was purchased by the Marquis de Lotbinière. He sold it in 1773, when it became the Collège Saint-Raphaël. It was destroyed by a fire in 1803.
