HMCS Medicine Hat (pennant J256) was a Bangor-class minesweeper that served with the Royal Canadian Navy during the Second World War. Entering service in 1941, the minesweeper was primarily used as a convoy escort in the Battle of the Atlantic and the Battle of the St. Lawrence. Following the war the vessel was laid up until reacquired during the Korean War. Never re-entering service with the Royal Canadian Navy, Medicine Hat was sold to the Turkish Navy in 1957. Renamed Biga, the minesweeper was discarded in 1963.
