Brock's Monument is a 56-metre (185 ft) column atop Queenston Heights in Queenston, Ontario, Canada, dedicated to Major General Sir Isaac Brock, one of Canada's heroes of the War of 1812. Brock, a British Army officer in charge of defending Upper Canada from a United States invasion, and one of his aides-de-camp, Lieutenant-Colonel John Macdonell, are interred at the monument's base on the heights above the battlefield where both fell during the Battle of Queenston Heights. The current monument was constructed between 1853 and 1856, which replaced an earlier Monument to Brock on the battlefield (1824–1840). Parks Canada maintains the monument, the most imposing feature of Queenston Heights National Historic Site. It is the fourth oldest war memorial in Canada.

Canadian war memorials are buildings, monuments, and statues that commemorate the armed actions in the territory encompassing modern Canada, the role of the Canadian military in conflicts and peacekeeping operations, and Canadians who died or were injured in a war. Much of this military history of Canada is commemorated today with memorials across the country and around the world. Canadian memorials commemorate the sacrifices made as early as the Seven Years' War to the modern day War on Terror. As Newfoundland was a British Dominion until joining Confederation in 1949, there are several monuments in Newfoundland and Labrador and abroad which were dedicated to Newfoundland servicemen and women.
