USS LST-849 was an LST-542-class tank landing ship in the United States Navy during World War II. Late in her U.S. Navy career, she was renamed Johnson County (LST-849)—after counties in Arkansas, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Missouri, Nebraska, Tennessee, Texas, and Wyoming—but never saw active service under that name. LST-849 was laid down on 10 November 1944 at Ambridge, Pennsylvania, by the American Bridge Co.; launched on 30 December 1944; sponsored by Mrs. William B. Hetzel; and commissioned on 16 January 1945, Lt. Emil C. Hetzel in command.
