HMS Stygian (pennant number P249) was a S-class submarine of the British Royal Navy, and the only ship so far to bear the name. The boat is listed as being a member of the fourth group, although she had the external stern torpedo tube fitted as in the third group.

After an eventful career in the Pacific during the Second World War, she was sold to be broken up for scrap on 28 October 1949, and finally scrapped by Metal Industries of Ardgour in August 1950.
