Two weeks prior to the end of hostilities in the Pacific, "Marquette" departed the east coast for Pearl Harbor. Arriving there on 23 August, she loaded cargo for the western Pacific and departed for Guam on 20 September. From Guam she continued on to Manus and Brisbane, where she picked up a cargo of food for the Philippines. Upon arrival at Samar, she discovered her cargo was no longer needed and had been transferred to UNRRA for use in Greece. She then proceeded to Piraeus, via Suez, discharged her cargo, and returned to Norfolk on 19 April 1946.
