HMS Psyche was a 54-gun fourth-rate frigate of the Royal Navy, constructed during the War of 1812 at the Kingston Royal Naval Dockyard in Kingston, Upper Canada. Built using frames shipped from Britain and assembled locally, Psyche was part of a British effort to bolster naval forces on the Great Lakes amid shifting power dynamics between Britain and the United States. Its keel was laid on October 31, 1814, and it was launched on December 25, 1814, making it the last major warship to begin service during the war. Designed initially as a 38-gun frigate, Psyche was later redesigned to carry 56 guns, featuring a spar deck that increased its armament. The vessel measured approximately 130 feet (39.6 meters) in length between perpendiculars, with a beam of 36 feet 7 inches (11.2 meters), a depth of hold of 10 feet 3 inches (3.1 meters), and a draft of 9 feet 8 inches (2.9 meters). It displaced around 7,691 tons burthen and had a crew complement of roughly 280 officers and sailors. Its armament included 28 24-pounder long guns on the lower deck and 28 32-pounder carronades on the upper deck. Psyche was completed in early 1815 and joined the Lake Ontario squadron under Sir James Yeo, later transferring command to Commodore Edward Owen in March of that year. However, following the conclusion of the War of 1812, the ship was hauled out and disarmed under the terms of the Rush–Bagot Treaty of 1816, which limited naval forces on the Great Lakes. Subsequently, Psyche remained laid up, with its frame stripped for preservation throughout the 1820s and 1830s. The decline of the naval dockyard at Kingston led to the sale or scuttling of its vessels, including Psyche, whose ultimate fate remains uncertain, with reports suggesting it was either sold, scuttled, or sank at its moorings in the late 1830s.
