HMS Seneschal was an S class submarine of the Royal Navy, and part of the Third Group built of that class. She was built by Scotts, of Greenock and launched on April 23, 1945. So far she has been the only ship of the Royal Navy to bear the name Seneschal, after the office.

She survived the Second World War, but endured several mishaps in post-war life. She suffered an explosion on 4 June 1947, and on 14 June 1952, she collided with the Danish frigate Thetis, south of the Isle of Wight. The submarine's periscope and radar mast were damaged.[1] In 1953 she took part in the Fleet Review to celebrate the Coronation of Queen Elizabeth II.[2] She was eventually sold, arriving at the yards of Clayton & Davie, Dunston, for breaking up on August 23, 1960.
