HMS Cornwall was an 80-gun third-rate ship of the line constructed for the Royal Navy, launched in 1692. As part of the 1691 Naval Programme, she was ordered on 12 March 1691 and built at Southampton by contractor John Winter. Her dimensions included a length of 156 feet 4 inches (47.7 meters) at the gundeck, a beam of 41 feet 6 inches (12.6 meters), and a depth of hold of 17 feet 3 inches (5.3 meters). Her tonnage was approximately 1,186 tons burthen. Initially, Cornwall's armament comprised a combination of demi-cannons, culverins, and smaller guns. The lower gundeck featured 24 broadside demi-cannons and two chase culverins, while the upper deck mounted 26 culverins on the broadside with two chase guns. The quarterdeck was armed with 16 six-pounder guns, complemented by six on the forecastle, and four three-pounders on the poop deck. In 1703, her armament was nominally revised to include 26 24-pounder guns on the lower gundeck and 28 12-pounder guns on the upper deck, though actual changes are uncertain. Cornwall's service record includes participation in significant conflicts such as the Nine Years' War, where she took part in the Battles of Barfleur and La Hougue in her first year. She was rebuilt at Rotherhithe from 1705 to 1706, after which she served in the Mediterranean during the War of the Spanish Succession, notably capturing a French convoy off Catalonia in May 1708. In 1722, she was ordered to be taken apart and rebuilt at Deptford according to the 1719 Establishment, relaunching in 1726 as an improved 80-gun vessel. Throughout her later career, Cornwall served primarily during peacetime in the Baltic and Mediterranean, though she saw action again during the War of the Austrian Succession, including participation in the Battle of Saint-Louis-du-Sud in 1748 and capturing a Spanish warship off Havana in 1749. She was repurposed as a prison ship in 1755, and her service ended in 1760. The vessel was ultimately broken up in 1761, marking the end of her maritime service.
