USS Kennebago (AO-81) was an Escambia-class replenishment oiler serving in the United States Navy during World War II.

Kennebago, a type T2-SE-A2 tanker hull, was built at Marinship, Sausalito, California, and launched on 9 May 1943, sponsored by Mrs. W. E. Waste, the ship was commissioned by the US Navy on 4 December 1943.

After an initial shakedown cruise off the west coast, Kennebago departed San Diego on 24 January 1944 for various bases in the Aleutians carrying fuel oil and aviation gasoline.

After a brief overhaul, Kennebago was again ready for operations in the Western Pacific, departing on 12 June, after brief stops in San Francisco, California, and Pearl Harbor.

After over a year, Kennebago was transferred to the United States Maritime Commission on 27 May 1947 as part of the National Defense Reserve Fleet.
