Fort Morgan is a historic masonry pentagonal bastion fort at the mouth of Mobile Bay, Alabama, United States. Named for American Revolutionary War hero Daniel Morgan, it was built on the site of the earlier Fort Bowyer, an earthen and stockade-type fortification involved in the final land battles of the War of 1812. Construction was completed in 1834, and it received its first garrison in March of the same year.

Fort Bowyer was a short-lived earthen and stockade fortification that the United States Army erected in 1813 on Mobile Point, near the mouth of Mobile Bay in what is now Baldwin County, Alabama, but then was part of the Mississippi Territory. The British twice attacked the fort during the War of 1812.
