USS Xenia (AKA-51) was an Artemis-class attack cargo ship in service with the United States Navy from 1945 to 1946.

Following shakedown, Xenia operated off the east coast with Service Force, Atlantic Fleet, from September 1945 until 17 April 1946, when she reported to the Commandant, 3rd Naval District, New York City, for disposal.

Decommissioned on 13 May 1946, Xenia was struck from the Navy list on 30 November 1946 and subsequently transferred to the government of Chile.

A July 1945 newspaper report stated that the Walsh-Kaiser Company had named each of its attack cargo ships after stars.
