USS LST-43 was a United States Navy LST-1-class tank landing ship used exclusively in the Asiatic-Pacific Theater during World War II. Like many of her class, she was not named and is properly referred to by her hull designation.

LST-43 was laid down on 19 June 1943, at Pittsburgh, Pennsylvania, by the Dravo Corporation; launched on 28 August 1943; sponsored by Mrs. C. A. Hill; and commissioned on 6 October 1943.^[2]

During World War II, LST-43 was assigned to the Asiatic-Pacific theater. She took part in the Occupation of Kwajalein and Majuro Atolls from 31 January to 8 February 1944.^[2]

She was destroyed and sunk during the West Loch disaster alongside 5 other LSTs at Pearl Harbor, on 21 May 1944.^[1]

LST-43 was struck from the Navy Register on 18 July 1944.^[1]

In 1945, she was raised but deemed too expensive to be repaired thus she was towed out to sea and sunk again as a target ship for torpedoes.^[2]
