HMS Alcmene was a 32-gun Alcmene-class fifth rate of the Royal Navy. This frigate served during the French Revolutionary and Napoleonic Wars under the command of several notable officers. Alcmene was active in several theatres of the war, spending most of her time cruising in search of enemy vessels or privateers, and escorting convoys. She fought at the Battle of Copenhagen in 1801 and served in the blockade of the French coasts during the later Napoleonic Wars until she was wrecked on the French coast in 1809.
