HMS Falmouth was a 50-gun fourth rate ship of the line built for Royal Navy in the 1690s.

She was the first of a batch of seven ships ordered during 1692 to the "123-ft" specification (the others being the Portland, Anglesea, Dartmouth, Rochester, Southampton and a replacement Norwich).

[4] The ship took part in the action of August 1702 and on the fourth and fifth days of the battle supported Admiral John Benbow's attacks when other members of the squadron failed to do so.

[5] On 4 August 1704 she was attacked by two French privateers of Rene Duguay-Trouin's squadron off the Isles of Scilly.

[6] The French sold her for merchant service at Brest in January 1706; she grounded near Buenos Aires in September 1706 with nearly all of her crew dead of illness and privation, and was burnt in February 1707.
