The Battle of Malcolm's Mills was a battle during the War of 1812 in which a force of American cavalry overran and scattered a force of Canadian and British militia. The battle was fought on November 6, 1814, near the village of Oakland in Brant County, Ontario, and was part of a series of battles fought by American Brigadier General Duncan McArthur on an extended raid into Upper Canada, known variously as McArthur's Raid or Dudley's Raid.
