HMS Kent, pennant number 54, was a County-class heavy cruiser built for the Royal Navy in the late 1920s. She was the lead ship of the Kent subclass. After completion the ship was sent to the China Station where she remained until the beginning of the Second World War, aside from a major refit in 1937–38. Kent hunted the German pocket battleship Admiral Graf Spee in the East Indies in late 1939 and then was reassigned to troop convoy escort duties in the Indian Ocean in early 1940. She was transferred to the Mediterranean in mid-1940, but was torpedoed shortly after arriving. The ship was under repair for a year and was then assigned to Home Fleet where she escorted convoys to and from North Russia for the next several years. In mid-1944 Kent escorted British aircraft carriers as their aircraft made attacks on German shipping and airfields in Norway. A few months later she was flagship of a force that intercepted a German convoy in Norwegian waters and sank two freighters and five escorts. The ship was paid off in early 1945 and placed in reserve until she was used as a target. Kent was sold for scrap in 1948.

The County class was a class of heavy cruisers built for the Royal Navy in the years between the First and Second World Wars. They were the first post-war cruisers constructed for the Royal Navy and were designed within the limits of the Washington Naval Treaty of 1922. Such ships, with a limit of 10,000 tons standard displacement and 8-inch calibre main guns may be referred to as "treaty cruisers".
