Fenix was an 80-gun ship of the line of the Spanish Navy, launched in 1749. She fought at the Battle of Cape St Vincent on 16 January 1780, as the flagship of Admiral Juan de Lángara. The Royal Navy captured Fenix during the battle, and commissioned her as the third rate HMS Gibraltar in March that year. She took part in the Battle of Cuddalore in 1783. Because Gibraltar served in the navy's Egyptian campaign (8 March to 8 September 1801), her officers and crew qualified for the clasp "Egypt" to the Naval General Service Medal that the Admiralty issued in 1847 to all surviving claimants.
