HMS Whitby was a Whitby-class or Type 12 anti-submarine frigate of the Royal Navy of the United Kingdom built by Cammell Laird and Co Ltd, Birkenhead.

The Whitby-class was designed as a class of specialist anti-submarine warships, intended to counter fast modern diesel-electric submarines.

Two Babcock & Wilcox water-tube boilers fed steam at 550 pounds per square inch (3,800 kPa) and 850 °F (454 °C) to two sets of geared steam turbines which drove two propeller shafts, fitted with large (2 feet (0.61 m) diameter) slow-turning propellers.

The machinery was rated at 30,000 shaft horsepower (22,000 kW), giving a speed of 29 knots (33 mph; 54 km/h).

In 1968 she undertook fishery protection duties off the coast of Greenland - the first ship to have visited those waters since 1966.
