Fort Henry National Historic Site is a 19th-century British military fortress situated on Point Henry between the mouth of Kingston harbour and a second natural harbour at the mouth of the Cataraqui River. It sits high on a natural cliff facing the confluence of the eastern end of Lake Ontario with the beginning of the St. Lawrence River. The designation refers to the fort, its redoubt, advanced battery, the former ''dead zone'' to the north and east, and the associated cultural resources found thereon.

Historic site not operated by Parks Canada - Fees continue to apply in 2017.
