Penetanguishene Naval Yard was a Royal Navy yard then a British Army base from 1813 to 1856 located at Penetanguishene in Upper Canada (present day Ontario).
Land was first acquired in 1798 near Penetanguishene and a base finally built in 1813, but it was abandoned in 1815 at the end of the War of 1812. It was reinstated in 1816 and remained in naval service until 1834.
The base served as the headquarters of the Lake Huron fleet of the Provincial Marine until 1834. The navy transferred the base to the army and continued until 1856. The base also served northwestern supply routes and provided general surveillance of the upper Great Lakes.
The navy base and army depot comprise 15 buildings, including:
