The Castle-class was a class of British offshore patrol vessels of the Royal Navy.

The Castle-class was designed by David K. Brown as a series of six offshore patrol vessels for the Royal Navy, designed in response to criticism of the previous Island-class for insufficient speed, non-optimal sea keeping and lack of a flight deck for rescue helicopters.

Their primary mission was to serve with the Fishery Protection Squadron, protecting both the fishing fleets and the oil and gas fields of the North Sea. In addition, they could also serve as minelayers, and had detergent spraying facilities on board for dispersing oil slicks.
