USS Westchester County (LST-1167) was a Terrebonne Parish-class tank landing ship built for the United States Navy at the tail end of the Korean War.

Designed under project SCB 9A and laid down as LST-1167 on 11 January 1952 by the Christy Corporation of Sturgeon Bay, Wisconsin; launched on 18 April 1953; sponsored by Mrs. Robert E. Wood; and commissioned on 10 March 1954.

After loading marines and equipment at Morehead City, North Carolina the tank landing ship sailed for exercises in the Caribbean on 11 January 1956.

On 28 February 1957 Westchester County embarked personnel and equipment at Morehead City and sailed to the Caribbean for amphibious training exercises, returning to Norfolk on 13 May.

The ship beached at Numazu, Japan on 5 September 1960 to commence a series of large scale amphibious exercises with SEATO forces.

The communist threat in Vietnam interrupted this training period and, on 13 May, Westchester County was underway for Subic Bay with a combat load of marines.

This exercise was delayed in Okinawa due to the Cuban Missile Crisis, which put United States ships on a worldwide alert.

Westchester County spent the time until 24 May shuttling marine personnel and equipment to Naha, Tsoying, and Numazu, Japan with interspersed upkeep periods at Yokosuka.

After a brief upkeep at Sasebo, Japan Westchester County took part in "Operation Flagpole", a joint amphibious exercise with the Republic of Korea Navy and Marines which concluded on 29 June.

July and August were spent in upkeep at Yokosuka, followed by "Exercise Bayonet Beach" on 5 September at Tong Po Pi, Korea.

At that time, due to the Tonkin Gulf Incident, Westchester County departed Naha for extended operations off Vietnam in the South China Sea.

Following upkeep at Yokosuka, Westchester County spent the period from 22 June to 15 August making Marine lifts to Da Nang and Chu Lai.

After reloading at Yokosuka, Westchester County transported Korean troops from Pusan, Korea to Qui Nhơn, South Vietnam.

From February throughout August, Westchester County transported troops and equipment to Qui Nhơn, Chu Lai, and Da Nang.

Until 4 October the ship steamed continuously on station off the Cà Mau Peninsula; refueling, replenishing, and serving as a base for the boats and crews who patrolled the coast of Vietnam to prevent infiltration by sea.

On 1 November while Westchester County lay anchored in the vicinity of Mỹ Tho, Vietnam two giant underwater explosions ripped through it, killing 26 men.

Viet Cong divers had attached limpet mines to the hull about amidships on the starboard side causing ruptured berthing compartments and fuel and storage tanks.

The remainder of 1969 was spent carrying personnel and equipment from Korea, Japan, and Okinawa to Vietnam with intermittent periods of repair and liberty.

During February, she conducted troop and equipment withdrawal from South Vietnam, then underwent restricted availability at Yokosuka beginning on 4 March.

On 2 August she relieved the Washoe County off the Cà Mau Peninsula for "Operation Solid Anchor", which consisted of fueling boats and helicopters.

Nine of Westchester County's sailors received the Combat Action Ribbon when they withstood enemy small arms and rocket fire while transiting the Bo De River.

From 6 August through 1 September, Westchester County assumed the administrative duties as SOPA (senior officer present afloat) in Hong Kong.

Following restricted availability at Yokosuka, the ship lifted personnel and equipment of a US Army security agency for transit to Pusan, and returned them to Okinawa on 6 December.

After SOPA duties at Hong Kong from 15 to 31 March, the ship resumed personnel and cargo transits to the Gulf of Tonkin until 30 August 1972.

After availability and shore bombardment exercises at Subic Bay which commenced on 14 March, Westchester County returned to Vietnam in support of "Operation End Sweep" which was completed on 18 July.

Westchester County was decommissioned on 30 August 1973 and arrived at the Inactive Ship Facility, Puget Sound Naval Shipyard, Bremerton, Washington on 30 November of that year.
