HMS Narwhal (N45) was one of the six ship class of Grampus-class mine-laying submarine of the Royal Navy. She was built by Vickers Armstrong, Barrow and launched 29 August 1935. She served in the Second World War in home waters. She was lost in the North Sea on 23 July 1940, probably sunk by German aircraft.

Narwhal had a brief but eventful career in wartime service. In February 1940 she helped HMS Imogen and HMS Inglefield to sink the German U-boat U-63 south east of the Shetland Islands and in May she torpedoed and sank the German troop transport Buenos Aires and torpedoed and damaged the troop transport Bahia Castillo. Bahia Castillo reached port but was declared a total loss.

Most of Narwhal's sinkings were caused by her mines. The German auxiliary minesweepers M 1302 / Schwaben, M 1102/H.A.W. Möllerthe, Gnom 7, Kobold 1 and Kobold 3; the German minesweeper M 11; German auxiliary submarine chaser UJ D / Treff VIII; the armed trawler V 1109 / Antares and the Swedish merchant Haga were all sunk on mines laid by Narwhal.

Ships damaged by mines laid by Narwhal included the armed trawler V 403 / Deutschland, the German merchants Togo and Clara M. Russ. The auxiliary minesweeper M 1101 / Fock und Hubert and the German merchant Palime also struck some of Narwhal's mines. They were successfully beached but declared total losses.
