HMS Hermes was a 20-gun Hermes-class sixth-rate flush-decked sloop-of-war built in Milford Dockyard to the lines of the ex-French Bonne Citoyenne. She was destroyed in 1814 to prevent her falling into American hands after grounding during her unsuccessful attack on Fort Bowyer on Mobile Point outside Mobile, Alabama.

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.
