USS Anacostia (AO-94) was a Escambia-class replenishment oiler acquired by the United States Navy for use during World War II.

She served in the Pacific Ocean Theater of operations late in the war, and returned home with one battle star.

The ship was laid down under a United States Maritime Commission contract (MC hull 1829) on 16 July 1944 at Sausalito, California, by the Marinship Corp., as Mission Alamo.

[1] Early in June, the oiler arrived in a designated fueling area off Okinawa and replenished the bunkers of various ships.

After completing this task, she sailed to Saipan to take on a cargo of gasoline to be distributed among forces there at Okinawa.

During August and September, Anacostia made two more round-trips between Ulithi and Okinawa, taking on fuel at the former port and discharging it at the latter.

During the next two years, Anacostia operated along the east coast of the United States; made numerous voyages through the Suez Canal to Ras Tanura, Saudi Arabia, and Bahrain to take on petroleum; visited ports in England and northern Germany; carried out several trips to Aruba to load up with petroleum; and paid calls to Japanese ports of Yokohama, Yokosuka, and Sasebo.

She was then turned over to the Maritime Administration and laid up with the National Defense Reserve Fleet in the James River.
