Canada's Hundred Days was the name given to the series of attacks made by the Canadian Corps between 8 August and 11 November 1918, during the Hundred Days Offensive of World War I by the French after the war. Reference to this period as Canada's Hundred Days is due to the role that the Canadian Corps repeatedly played as a spearhead during offensives.

The Hundred Days Offensive was a series of massive Allied offensives that ended the First World War. Beginning with the Battle of Amiens on the Western Front, the Allies pushed the Imperial German Army back, undoing its gains from the German spring offensive.
