HMS Trusty (N45) was a T-class submarine of the Royal Navy. She was laid down by Vickers Armstrong, Barrow and launched in March 1941.

Trusty served in the Mediterranean and in the Pacific Far East. She sank the Italian merchant Eridano in December 1941, and on reassigning to the Pacific, she sank the Japanese merchant cargo ship Toyohashi Maru and damaged the Japanese troop transport Columbia Maru.^[1]
