Kamoi (神威, "Divine Authority") was an oiler/seaplane tender/flying boat tender of the Imperial Japanese Navy, serving from the 1920s through World War II.

Somewhere around the end of 1932, she was converted to seaplane tender for January 28 Incident at Uraga Dock Company, an overhaul that was finished in February 1933.

On 28 January 1944, Kamoi sustained heavy damage in an attack by the submarine USS Bowfin off Makassar.

Three days later, she sustained heavy damage in an attack by a United States Navy submarine outside Manila Bay.

On 5 April 1945, with repairs still incomplete, she was once again damaged by air raid, later sinking in shallow water.
