USS Prentiss (AKA-102) was a Tolland-class attack cargo ship in service with the United States Navy from 1945 to 1946.

After shakedown in the Chesapeake Bay area, Prentiss sailed from Norfolk for Pearl Harbor, arriving on 13 April.

Following this spirited reception, unloading of her volatile cargo was speedy; she departed the area on 27 June.

On 15 October 1947 the Maritime Administration sold the ship to the Aluminum Company of America, who renamed her Alcoa Ranger.

On 18 December 1969 she ran aground off the coast of Nicaragua while en route from Lake Charles, Louisiana to Saigon (now known as Ho Chi Minh City), South Vietnam.
