USS LST-801 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-801 was laid down on 6 September 1944 at Jeffersonville, Indiana, by the Jeffersonville Boat and Machine Co.; launched on 14 October 1944; sponsored by Miss Jane E. Calhoun; and commissioned on 8 November 1944, Lt. Herbert G. Whitehead, USNR, in command. In Argentine Navy service, Don Antonio was renamed ARA Cabo Buen Tiempo and redesignated BDT-13 (Buque Desembarco de Tanques). She was retired in 1963.
