HMS Tanatside was a Hunt-class destroyer of the Royal Navy. She was launched at Yarrow in April 1942. Ships of this class were designed as cheap, easily built vessels for convoy escort and antisubmarine duties. She was named like her sisters after a fox hunt, in her case one in North Wales. War bonds were issued to finance the building of warships. Tanatside was funded by people from Tregaron, Aberaeron, New Quay, Aberystwyth and Teifiside, in a nod to the ship's name. Plaques were presented to each of these townships. During a Warship Week held between 14 and 21 March 1942 the civil community of the Welsh county of Cardiganshire adopted the ship.
