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

Tumult displaced 1,710 long tons (1,740 t) at standard load and 2,530 long tons (2,570 t) at deep load. She had an overall length of 362 feet 9 inches (110.6 m), a beam of 35 feet 8 inches (10.9 m) and a deep draught of 14 feet 6 inches (4.4 m). She was powered by two Parsons geared steam turbines, each driving one propeller shaft, using steam provided by two Admiralty three-drum boilers. 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). Tumult carried a maximum of 615 long tons (625 t) of fuel oil that gave her a range of 4,675 nautical miles (8,658 km; 5,380 mi) at 20 knots (37 km/h; 23 mph). Her complement was 170 officers and ratings.

The ship was armed with four 45-calibre 4.7-inch (120 mm) Mark XII guns in dual-purpose mounts. For anti-aircraft (AA) defence, Tumult had one twin mount for Bofors 40 mm guns and four twin 20-millimetre (0.8 in) Oerlikon . She was fitted with two above-water quadruple mounts for 21-inch (533 mm) torpedoes. Two depth charge rails and four throwers were fitted for which 70 depth charges were provided.
