The Pathfinder-class cruiser was a pair of scout cruisers built for the Royal Navy in the first decade of the 20th century. Both ships participated in World War I; one ship was sunk shortly after the war began, but the other survived the war to scrapped shortly after its end.

In 1901–02, the Admiralty developed scout cruisers to work with destroyer flotillas, leading their torpedo attacks and backing them up when attacked by other destroyers. In May 1902, it requested tenders for a design that was capable of 25 knots (46 km/h; 29 mph), a protective deck, a range of 2,000 nautical miles (3,700 km; 2,300 mi) and an armament of six quick-firing (QF) 12-pounder 18 cwt guns, eight QF 3-pounder (47 mm) guns and two 18-inch (450 mm) torpedo tubes. It accepted four of the submissions and ordered one ship from each builder in the 1902–03 Naval Programme and a repeat in the following year's programme.

The two ships from Cammell Laird became the Pathfinder class. Four more 12-pounders were added to the specification in August. The ships had a length between perpendiculars of 370 feet (112.8 m), a beam of 38 feet 9 inches (11.8 m) and a draught of 15 feet 2 inches (4.6 m) at deep load. They displaced 2,940 long tons (2,987 t) at normal load and 3,240 long tons (3,292 t) at deep load. Their crew consisted of 289 officers and other ranks.
