HMS Supreme was an S class submarine of the Royal Navy, and part of the Third Group built of that class. She was built by Cammell Laird and launched on February 24, 1944. So far she has been the only ship of the Royal Navy to bear the name Supreme.

She survived the Second World War, spending most of it in the Pacific Far East, where she sank thirteen Japanese sailing vessels, six Japanese coasters, a Japanese tug and a barge, and a small unidentified Japanese vessel. Supreme also attacked what is thought to be a Japanese auxiliary patrol vessel.[1]

Supreme was eventually paid off and broken up at Troon in July 1950.
