USS Pitkin County (LST-1082) was an LST-542-class tank landing ship built for the United States Navy during World War II.

After shakedown to St. Andrews Bay, Florida, and alterations at Mobile, the new tank landing ship loaded pontoon barges at Gulfport, Mississippi, and departed on 24 March 1945 with 90 Navy passengers who were disembarked in the Panama Canal Zone.

Fourteen days later she stood out of Pearl Harbor with 210 Marines and their equipment bound for occupation duty in Japan, and reached Sasebo on 23 September.

She fitted out in the Puget Sound Naval Shipyard, trained out of San Diego, and sailed on 19 December for Japan via Pearl Harbor and Midway Island.

Returning to Yokosuka on 6 July, LST–1082 carried out amphibious assault training with Army field artillery troops along the coast of Japan before transporting them to Pusan.

She spent much of the next eight months in Marine amphibious assault landing exercises that took her from the shores of Japan to the beaches of Okinawa, Iwo Jima, and Inchon.

Named USS Pitkin County (LST-1082) on 1 July 1955, she operated on the West Coast until she decommissioned at San Diego on 1 September 1955 and entered the Pacific Reserve Fleet.

After debarking Marines, she began shuttle operations between Da Nang and Chu Lai until sailing for Guam on 21 December, arriving at Apra Harbor on 2 January 1967.

On Christmas Eve she sped to assist the merchant tug Makah ablaze in Vũng Tàu Harbor, and extinguished the fires saving the stricken and abandoned ship.

Pitkin County was decommissioned on 1 September 1971, and struck from the Naval Vessel Register on 1 April 1975 and transferred to the Defense Reutilization and Marketing Service (DRMS) for disposal.

However, she was then sold to Max Rouse & Sons, Beverly Hills, California, and taken in hand by Marine Industries, Tacoma, Washington for conversion for commercial use.

She arrived at Piraeus, Greece having been acquired by Maritime & Commercial Co. Argonaftis S.A., Panama (Greek flag) and was renamed Petrola 144, on 6 June 1978.
