HMS Spiteful (Pennant number P227) was a third-batch S-class submarine built for the Royal Navy during the Second World War.

[2] For surface running, the boats were powered by two 950-brake-horsepower (708 kW) diesel engines, each driving one propeller shaft.

[3] On the surface, the third-batch boats had a range of 6,000 nautical miles (11,000 km; 6,900 mi) at 10 knots (19 km/h; 12 mph) and 120 nmi (220 km; 140 mi) at 3 knots (5.6 km/h; 3.5 mph) submerged.

[4] It is uncertain if Spiteful was completed with a 20-millimetre (0.8 in) Oerlikon light AA gun or had one added later.

She sank a number of Japanese vessels with gunfire on 30 June, 2 July, and 14 December.
