USS Mahoning County (LST-914) was an LST-542-class tank landing ship built for the United States Navy during World War II.

Shortly afterward the LST joined Training Group Command, Atlantic Fleet, and operated along the east and gulf coasts until early in 1945.

For the next four months the ship carried men and equipment between Saipan and Okinawa, making occasional calls at Tinian and Guam.

[4] With the outbreak of hostilities in Korea and the consequent urgent need for ships, LST‑914 recommissioned at Yokosuka, Japan, 26 August 1950.

She embarked units of the 1st Marine Division at Pusan and transported them around the peninsula for the 15 September, Inchon invasion, one of the decisive amphibious assaults of history, which routed the North Korean Army.

Following Inchon, for which her task element was awarded the Navy Unit Commendation, the LST participated in the Wonsan operations and in the evacuation of Hungnam, 10–24 December.
