HMS Zetland was a Royal Navy Type II , named after the Zetland Hunt.

Built by Yarrow Shipbuilders, Glasgow and launched on 7 March 1942. She was commissioned on 27 June 1942 with the pennant number L59. Zetland was given to the Royal Norwegian Navy and commissioned as HNoMS Tromsø. She was sold for breaking up in 1965.

Construction HMS Zetland was ordered from Yarrows on 20 December 1939, one of 16 Type II Hunt-class destroyers ordered from various shipbuilders on that date, (including two from Yarrows).English 1987, p. 17. The Hunts were meant to fill the Royal Navy's need for a large number of small destroyer-type vessels capable of both convoy escort and operations with the fleet. The Type II Hunts differed from the earlier ships in having increased beam in order to improve stability and carry the ships' originally intended armament.English 1987, pp. 11–12.

Zetland was laid down at Yarrow's Scotstoun, Glasgow shipyard on 2 October 1940, was launched on 15 January 1942 and completed on 7 May 1942.

Zetland was long between perpendiculars and overall. The ship's beam was and draught . Displacement was standard and under full load. Two Admiralty boilers raising steam at and fed Parsons single-reduction geared steam turbines that drove two propeller shafts, generating at 380 rpm. This gave a speed of .Lenton 1970, p. 89. of oil were carried, giving a design range of (although in service use, this dropped to ).English 1987, p. 12.

The ship's main gun armament was six 4 inch (102 mm) QF Mk XVI dual purpose (anti-ship and anti-aircraft) guns in three twin mounts, with one mount forward and two aft. Additional close-in anti-aircraft armament was provided by a quadruple 2-pounder "pom-pom" mount and two single Oerlikon 20 mm cannon mounted in the bridge wings.Gardiner and Chesneau 1980, p. 47.Lenton 1970, pp. 85, 89. Power-operated twin Oerlikon mounts replaced the single Oerlikons during the war.Whitley 2000, p. 145. Up to 110 depth charges could be carried.Lenton 1970, p. 87.Friedman 2008, p. 319. The ship had a complement of 168 officers and men.

Second World War service During the Second World War, Zetland saw service in the Atlantic (1942–43), Malta Convoys (1942), north Africa (1942–43), Mediterranean (1943–44), Aegean (1944), Adriatic (1944) and Operation Dragoon, the landings in southern France in 1944.

Air Raid on Bari Zetland was one of two Hunt-class destroyers that were damaged in the air raid on Bari on 2 December 1943. An ammunition ship was hit and exploded, spreading her cargo of mustard gas over the harbour and town. Zetland was near-missed by a German bomb, and subject to blast and fragment damage from the explosion of two nearby merchant ships. Zetlands sister ship, was damaged more seriously. Zetland towed Bicester to Taranto for repairs.Rohwer and Hümmelchen 1992, p. 249.English 1987, pp. 35, 105.H.M. Ships Damaged or Sunk by Enemy Action 1952, p. 247. There were so many mustard gas casualties that, on arrival in Taranto, the ships had to ask for assistance to enter the harbour as all navigating officers had their vision impaired by this chemical weapon.

Postwar service Between June and October 1945 Zetland was in refit in Alexandria, before returning to the UK. On 20 April 1946 she paid off into reserve and was assigned to the Solent Division Royal Naval Volunteer Reserve (RNVR) as a drill ship. On 2 September 1954 she was lent to Norway. She was broken up in 1965 at Sarpsborg shipbreakers.Critchley, Mike, "British Warships Since 1945: Part 3: Destroyers", Maritime Books: Liskeard, UK, 1982. , page 39
