The 49th Infantry Division was a unit of the United States Army National Guard during the Cold War.
It was formed from the 52nd Infantry Division, which had itself been activated in 1946 during the expansion of National Guard after the end of World War II. The 52nd was renumbered as the 49th in 1947 due to the centennial of the California Gold Rush. It was inactivated in 1968 during a reorganization of the Army National Guard.
