The 9th Canadian Infantry Brigade was an infantry brigade of the Canadian Army that saw active service during World War I and World War II as part of the 3rd Canadian Infantry Division. The brigade fought on the Western Front during World War I from January 1916 to November 1918, and in Normandy and north-west Europe in 1944–1945 during World War II. It was a square formation of four infantry battalions during World War I, but was reduced to a triangular formation of three battalions during World War II.
