USS Lafayette County (LST-859) was an LST-542-class tank landing ship built for the United States Navy during World War II.

Originally laid down as LST-859 by the Chicago Bridge & Iron Company of Seneca, Illinois on 26 September 1944; launched on 15 December 1944, sponsored by Mrs. Elsie M. Marcum; and commissioned at Algiers, Louisiana on 6 January 1945.

On 31 July she departed San Diego for Pearl Harbor; and after arriving on 11 August, she sailed the 18th on a cargo run to American bases in the Hawaiian Islands.

For daring bravery and heroic performance of duty on "Red Beach", the gallant and aggressive landing ship tanks of Task Element 90.32, including LST-859, received the Navy Unit Commendation.

In addition, she shuttled cargo along the Japanese coast; and, following the end of conflict on the Korean peninsula, she continued her important supply runs until departing Yokosuka on 18 May 1954 for Pearl Harbor where she arrived on 3 June.

LST-859 resumed her pattern of cargo runs to Pacific bases on 20 June, and during the remainder of the year steamed primarily between Pearl Harbor and Midway.

Named USS Lafayette County (LST-859) on 1 July 1955, she returned to Pearl Harbor on 31 August to resume cargo shuttle runs among the Hawaiian Islands.

Lafayette County served principally in the Hawaiian chain during the next three years, although from 3 March to 13 April 1957 she carried out cargo runs to bases in the Marshalls.

She decommissioned on 15 August 1958 at Pearl Harbor and was transferred to the custody of the Republic of China under the Military Assistance Program, where she served the Chinese Nationalist Navy as ROCS Chung Cheng (LST-224).
