HMS Tremendous was a 74-gun third rate ship of the line of the Royal Navy, launched on 30 October 1784 at Deptford.
Throughout May 1794 Tremendous, whilst under the command of Captain James Pigott, participated in the campaign which culminated in the Battle of the Glorious First of June. Pigott had kept his ship too far to windward of the enemy to make best use of his guns in the battle; Tremendous's captain was one of several denied medals afterwards.
On 11 December 1799, she destroyed the Preneuse at the Battle of Port Louis.
On 21 April 1806, she fought the inconclusive Action of 21 April 1806 against Canonnière
On 13 May she was present at the surrender of Naples during the Neapolitan War. A British squadron, consisting of Tremendous, the frigate Alcmene, the sloop Partridge, and the brig-sloop Grasshopper blockaded the port and destroyed all the gunboats there. Parliament voted a grant of £150,000 to the officers and men of the squadron for the property captured at the time, with the money being paid in May 1819.
Early in September 1811, Primus, carrying tar and hemp, Worksam, in ballast, Experiment, carrying iron, Columbus, carrying linseed, Neptunus, carrying timber, and Hector, carrying sundry goods, came into Yarmouth. They were prizes to Tremendous, Ranger, Calypso, Algerine, Musquito, Earnest. and Portia.
