USS Oklawaha (AO-84) was a Escambia-class replenishment oiler acquired by the United States Navy for use during World War II.

Following conversion and fitting out for carrying potable water, and after shakedown operations off the west coast, Ocklawaha sailed on 19 May 1944 for duty with Service Forces Pacific (ServPac) during the remainder of World War II.

She arrived at Eniwetok, Marshall Islands, in June 1944 to provide potable water for and to become a part of the forces being assembled there for the Marianas operations.

During this period, she delivered water to 809 ships, mostly landing vessels actively engaged in amphibious operations against the Japanese.

Ocklawaha returned to San Pedro, California, on 1 June 1945 for overhaul, then deployed again to the Western and South West Pacific areas where she continued her service operations until 29 May 1946.
