RAAF Tanambogo was a Royal Australian Air Force seaplane advanced operating base on the islands of Tanambogo, Gaomi and Gavutu, British Solomon Islands, constructed in 1939. Tanambogo and Gavutu were connected by causeway.

No. 11 and No. 20 Squadrons flying PBY 4 Catalinas operated from the base until shortly before it was occupied by the Japanese 3rd Kure Special Naval Landing Force in May 1942. Tanambogo was later utilised by the Yokohama and Yokusuka Air Groups.Frank, p. 79.

The base was liberated by the 1st Parachute Battalion and 3rd Battalion, 2nd Marines during a battle that was fought between 7 and 9 August 1942, and resulted in 70 US marines and 476 Japanese being killed; prior to the battle the base was heavily damaged by naval gunfire as part of preparatory fires to soften Japanese defences.{{cite web |url=http://pacificwrecks.com/airfields/solomons/gavutu/ |title=Tulagi Seaplane Base (Gavutu, Tanambogo) |publisher=Pacific Wrecks |accessdate=11 October 2014}}{{cite web |url=http://www.history.navy.mil/photos/events/wwii-pac/guadlcnl/guad-1g.htm |archive-url=https://web.archive.org/web/20020213170906/http://www.history.navy.mil/photos/events/wwii-pac/guadlcnl/guad-1g.htm |url-status=dead |archive-date=13 February 2002 |title=Conquest of Tanambogo and Gavutu Islands, 7–8 August 1942 |work=Online Library of Selected Images |publisher=Department of the Navy, Naval Historical Center |accessdate=11 October 2014}}
