The American Can Company Building is a historic former factory in the Northside neighborhood of Cincinnati, Ohio, United States. Built in 1921, it is a concrete building with a concrete foundation and an asphalt roof; five stories tall, it has a total floor space of approximately 180,000 square feet (17,000 m2). Built by the American Can Company, the factory was used to manufacture can-making machines, rather than producing the cans itself; it remained in operation until closure in 1963. Two years later, it was reopened by the Cleveland Machine Company, which used its first floor for machining purposes; after their departure in 1978, it sat almost totally unused, with the only exceptions being small businesses such as T-shirt printers and warehouse operators.
