RHS Kanaris (L53) (Greek: ΒΠ Κανάρης) was a Type III Hunt-class destroyer that was originally built for the British Royal Navy as HMS Hatherleigh.

The Hunt class was 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.

Two Admiralty boilers raising steam at 300 pounds per square inch (2,100 kPa) and 620 °F (327 °C) fed Parsons single-reduction geared steam turbines that drove two propeller shafts, generating 19,000 shaft horsepower (14,000 kW) at 380 rpm.

Before her completion, she was transferred to the Royal Hellenic Navy and commissioned on 27 July 1942, in order to relieve heavy losses of ships sustained by Greece during the German invasion of 1941.

She was named after Admiral Konstantinos Kanaris, hero of the Greek War of Independence, and later Prime Minister of Greece.
