Six ships of the Royal Navy have borne the name HMS Perseus, after the Greek hero Perseus:
HMS Perseus (1776) was a 20-gun sixth rate launched in 1776; she was the first vessel of the Royal Navy to be sheathed in copper.[1] She was converted to a bomb vessel in 1799 and was broken up in 1805.
HMS Perseus (1812) was a 22-gun sixth rate launched in 1812. She was used for harbour service from 1818 and was broken up in 1850.
HMS Perseus (1861) was a Camelion-class wooden screw sloop launched in 1861. She was used for harbour service from 1886, was renamed HMS Defiance II in 1904 and was probably sold in 1912.
