Navy Island Royal Naval Shipyard was a Royal Navy yard in Ontario.
Located on Navy Island in the Niagara River, it served as a French naval base in the early 18th century and was acquired by the British in 1763. The Royal Navy used it for their Lake Erie fleet during the War of 1812. Abandoned by the navy with the passage of the Rush-Bagot Treaty in 1817, it was formally acquired by Canada in 1822. It is now a National Historic site and managed by the Niagara Parks Commission.
