Battlefield of Fort George National Historic Site is located near Fort George National Historic Site in Niagara-on-the-Lake, Ontario. The rolling open landscape near the shore of Lake Ontario at Two Mile Creek was the site of one of the fiercest and most important battles of the War of 1812. There are no extant remains of the 1813 battle between American invading forces and British regulars and Canadian militia; however, a cairn and plaque erected by the Historic Sites and Monuments Board of Canada (HSMBC) marks the northeast corner of the battle site. Official recognition refers to the irregular polygon encompassing the battlefield.

The site is not open to the public.
