Kamikawa Maru (神川丸) was a seaplane tender in the Imperial Japanese Navy (IJN).

The ship was initially built at Kawasaki's Kōbe Shipyard and launched on 13 December 1936 as a merchant vessel for the Kawasaki Kisen K. K. Line.

On 18 September 1937 the IJN requisitioned her as an aircraft transport ship and she was refitted in 1939 as a seaplane tender.

On May 29, 1943, Kamikawa Maru was torpedoed and sunk by the submarine USS Scamp approximately 250 miles (400 km) northwest of Kavieng, New Ireland at 01°36′S 150°24′E / 1.600°S 150.400°E / -1.600; 150.400.
