HMS Pathfinder was a P-class destroyer built for the Royal Navy during the Second World War.

The turbines developed a total of 40,000 shaft horsepower (30,000 kW) and gave a maximum speed of 36 knots (67 km/h; 41 mph).

The ships carried a maximum of 500 long tons (510 t) of fuel oil that gave them a range of 3,850 nautical miles (7,130 km; 4,430 mi) at 20 knots (37 km/h; 23 mph).

[1] Pathfinder was armed with four QF 4-inch Mark V guns in single mounts, two pairs [superfiring] fore and aft.

Her light anti-aircraft suite was composed of one quadruple mount for 2-pounder "pom-pom" guns and four single Oerlikon 20 mm cannon.
