HMS Trespasser was a British submarine of the third group of the T class. She was built as P312 by Vickers Armstrong, Barrow, and launched on 29 May 1942. So far she has been the only ship of the Royal Navy to bear the name Trespasser.

She was one of only two T-class submarines completed without an Oerlikon 20 mm anti-aircraft gun, the other being HMS P311.
