The second USS Bancroft (DD-256) was a Clemson-class destroyer in the United States Navy, which briefly served in 1919. Placed in reserve, the ship lay idle before being reactivated for World War II. She was transferred to the Royal Canadian Navy in 1940, where she served as HMCS St. Francis (I93) in the Battle of the Atlantic escorting convoys. The ship was declared surplus in April 1945, sold for scrap and sank on the way to the breakers after a collision in July.
