HMCS Milltown (pennant J317) was a Bangor-class minesweeper that served with the Royal Canadian Navy during the Second World War. The vessel entered service in 1942 and took part in the Battle of the Atlantic, Battle of the St. Lawrence and the invasion of Normandy. Milltown was laid up following the war, but reacquired in 1952 during the Korean War. The ship never re-entered service with the Royal Canadian Navy and was sold for scrap in 1959.
