USS LST-921 was an LST-542-class tank landing ship in the United States Navy. Like many of her class, she was not named and is properly referred to by her hull designation.

LST-921 was laid down on 1 May 1944, at Hingham, Massachusetts, by the Bethlehem-Hingham Shipyard; launched on 2 June 1944; and commissioned on 23 June 1944.^[3][2]

LST-921 was torpedoed by U-667 off the channel entrance to Bristol, England, on 14 August 1944, at 16:54, while sailing with convoy EBC 72. She was struck by one torpedo on her aft port side which broke the stern off. Two officers, along with 41 enlisted men, were lost, with the survivors being picked up by her sister ship LST-920 and the British Grimsby-class sloop Londonderry. The bow section was towed to port and stripped prior to decommissioning and disposal of the hulk. The ship was decommissioned on 29 September 1944, and struck from the Navy list on 14 October 1944. Her hulk was later used as a floating machine ship for the US Army in Antwerp, Belgium.^[3][4]
