HMS Prince of Wales was a King George V-class battleship of the Royal Navy that was built at the Cammell Laird shipyard in Birkenhead. Despite being sunk less than a year after she was commissioned, Prince of Wales had an extensive battle history, first seeing action in August 1940 while still being outfitted in her drydock, when she was attacked and damaged by German aircraft. In her brief career, she was involved in several key actions of the Second World War, including the May 1941 Battle of the Denmark Strait, where she scored three hits on the German battleship Bismarck, forcing Bismarck to abandon her raiding mission and head to port for repairs. Prince of Wales later escorted one of the Malta convoys in the Mediterranean, during which she was attacked by Italian aircraft. In her final action, she attempted to intercept Japanese troop convoys off the coast of Malaya as part of Force Z when she was sunk by Japanese aircraft on 10 December 1941, two days after the attack on Pearl Harbor.

She was sunk alongside her consort, the battlecruiser HMS Repulse, in an attack by 85 Mitsubishi G3M and G4M bombers of the Japanese navy air service. Prince of Wales and Repulse became the first capital ships to be sunk solely by air power on the open sea, a harbinger of the diminishing role this class of ships was subsequently to play in naval warfare. The wreck of Prince of Wales lies upside down in 223 feet (68 m) of water, near Kuantan, in the South China Sea.

In the aftermath of the First World War, the Washington Naval Treaty was drawn up in 1922 in an effort to stop an arms race developing between Britain, Japan, France, Italy and the United States. This treaty limited the number of ships each nation was allowed to build and capped the tonnage of all capital ships at 35,000 tons. These restrictions were extended in 1930 through the Treaty of London, however, by the mid-1930s Japan and Italy had withdrawn from both of these treaties, and the British became concerned about a lack of modern battleships within their navy. As a result, the Admiralty ordered the construction of a new battleship class: the King George V class. Due to the provisions of both the Washington Naval Treaty and the Treaty of London, both of which were still in effect when the King George Vs were being designed, the main armament of the class was limited to the 14-inch (356 mm) guns prescribed under these instruments. They were the only battleships built at that time to adhere to the treaty, and even though it soon became apparent to the British that the other signatories to the treaty were ignoring its requirements, it was too late to change the design of the class before they were laid down in 1937.

Prince of Wales was originally to be named King Edward VIII but upon the abdication of Edward VIII the ship was renamed at Cammell Laird's shipyard in Birkenhead on 1 January 1937, before being laid down. She was launched on 3 May 1939. She was still fitting out when war was declared in September, causing her construction schedule, and that of her sister, King George V, to be accelerated. Nevertheless, the late delivery of gun mountings caused delays in her outfitting.

In early August 1940, while she was still being outfitted and was in a semi-complete state, Prince of Wales was attacked by German aircraft. One bomb fell between the ship and a wet basin wall, narrowly missing a 100-ton dockside crane, and exploded underwater below the bilge keel, about six feet from the ship's port side in the vicinity of the aft group of 5.25-inch guns. The shell plating buckled over a distance of 20 to 30 feet (6.1 to 9.1 m), rivets were sprung and there was considerable flooding in the port outboard compartments in the area of damage, causing a ten-degree list to port. The flooding was severe, because final compartment air tests had not yet been made and the ship did not have her pumping system in operation.

The water was pumped out through the joint efforts of a local fire company and the shipyard, and Prince of Wales was later dry-docked for permanent repairs. This damage and the problem with the delivery of her main guns and turrets delayed her completion. As the war progressed there was an urgent need for capital ships, and so her completion was advanced by postponing compartment air tests, ventilation tests and thorough testing of her bilge, ballast and fuel-oil systems.

Prince of Wales displaced 36,727 long tons (37,300 t) as built and 43,786 long tons (44,500 t) fully loaded. The ship had an overall length of 745 feet (227.1 m), a beam of 103 feet (31.4 m) and a draught of 29 feet (8.8 m). Her designed metacentric height was 6 feet 1 inch (1.85 m) at normal load and 8 feet 1 inch (2.46 m) at deep load.
