USNS Harris County (T-LST-822) was an LST-542-class tank landing ship built for the United States Navy during World War II.

She touched Eniwetok on 27 March, then arrived Ulithi on 7 April to prepare for participation in the battle of Okinawa, begun a week earlier.

During her three weeks at Okinawa she survived 18 enemy air raids and carried vitally needed supplies for ground forces.

She departed Yokosuka on 20 July, arrived San Diego on 9 August, and spent the next nine months participating in amphibious training along the West Coast.

Operating out of Yokosuka and Sasebo, she steamed to ports along the coast of Korea from Inchon and Koje Do to Pusan and Pohang.

Arriving Yokosuka on 25 February, she resumed supply duty in support of US forces in the Far East, and during the next five months steamed to Korea, Okinawa, and along the coast of Japan.

Between 29 August and 2 October she carried refugees, cargo, and military equipment from Haiphong to Nha Trang, South Vietnam.

For almost two months she conducted supply and survey operations in the ice-filled Arctic Ocean north of Alaska.

Crewed by civilians, Harris County continued operating along the coast of Alaska and into the southern reaches of the Arctic Ocean.

Steaming via Seward, Alaska she arrived Pearl Harbor on 12 February to begin duty as a survey support ship.

Thereafter Harris County operated throughout the Pacific from Hawaii to New Guinea while carrying supplies and supporting ocean survey projects.

Subsequently, placed out of service and struck from the Naval Vessel Register, the ship was sold to the Philippines on 13 September 1976.
