The third HMS Shannon was a 36-gun Perseverance-class frigate of the British Royal Navy built at Frindsbury on the River Medway on the Thames Estuary. She was completed on 3 September 1803 during the Napoleonic Wars. Her name was changed from Pallas to Shannon shortly before construction, traditionally an omen of bad luck for a ship. In her case, she was wrecked within three months of her being launched.
