The Duluth Armory is a former armory and event venue in the East Hillside neighborhood of Duluth, Minnesota, United States. It was built in 1915 for the National Guard and naval militia, and expanded in 1941. From the beginning the National Guard also rented out the drill hall as an event venue, as it provided a larger and more flexible space than any other local venue until the construction of the Duluth Arena-Auditorium in 1966.
