HMS Narcissus was a Sphinx-class 20-gun sixth-rate post ship of the Royal Navy launched in 1781. Most notably in 1782, under the command of Captain Edward Edwards, a mutiny occurred aboard the vessel which resulted in the hanging of six men, and the flogging of an additional fourteen. Captain Edwards went on to command HMS Pandora, which was assigned to carry the Bounty mutineers back to England. The Narcissus was wrecked in 1796.
