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).
