Fort Howard was a 19th-century fortification in the north central United States, built by the U.S. Army. It was located along the west bank of the Fox River in Green Bay, Wisconsin.Along with Fort Crawford at Prairie du Chien, Fort Howard was constructed during the War of 1812 to protect the Fox-Wisconsin Waterway, an important regional trade and travel route between Lake Michigan and the Mississippi River, from British invasion. The fort was built at the site of the earlier French Fort La Baye (and renamed Fort Edward Augustus by the British in 1761).During an outbreak of malaria in 1820, the garrison moved to Camp Smith on higher ground nearby. Fort Howard was reoccupied two years later. Abandoned again in 1841, when the garrison was sent to Florida during the Seminole Wars, the fort was officially decommissioned in 1853.Following the fort's closure its buildings fell into decay. Several structures were subsequently removed to the Camp Smith site, where they are now part of the Heritage Hill State Historical Park. Three of the fort's remaining structures are listed on the National Register of Historic Places: the hospital, hospital ward, and officers' quarters.
