Poole and Hunt Company Buildings is a national historic district in the Hampden neighborhood of northwestern Baltimore, Maryland, United States. It is a complex of fieldstone and brick buildings on a 20-acre (81,000 m2) site. They were erected in 1853 and enlarged periodically as the need arose for the Poole and Hunt Engineering Company, who produced machinery and castings for a world-wide market from 1853 to 1889. A devastating fire on September 17, 1995 destroyed much of the fabric of the machine shop.
It was added to the National Register of Historic Places in 1973.
