Kiska Harbor Seaplane Base was located inside Kiska Harbor with shore facilities at "Main Camp" on eastern Kiska Island in the Rat Island Group (Rat Islands) in the Aleutian Islands of Alaska. Prewar, this location was used by the U.S. Navy (USN) as a seaplane landing area to support the small garrison manning Kiska Station (Kiska Weather Station) on Kiska Island.

Wartime History
On June 6, 1942 five hundred Imperial Japanese Navy (IJN) No. 3 Special Naval Landing Force (3rd SNLF) land at Kiska Harbor. The Japanese Navy developed the area around Kiska Harbor into their main base area known as "Main Camp".

The Japanese further developed the area as a seaplane anchorage and forward base defended by anti-aircraft guns and coastal guns. By October 1942 a large metal hanger was built to protect the seaplanes. Nearby was a submarine base with a ramp and pens for Type A midget submarines.

Wartime History
During early June 1942 used by the Imperial Japanese Navy (IJN) as a forward seaplane base and submarine base. Starting on June 8, 1942 bombed by American aircraft. Used by the Japanese until they withdrew from Kiska on July 23, 1943. Afterwards, American planes continued to bomb the area until August 17, 1943.
