The Battle of Empress Augusta Bay, on 1–2 November 1943—also known as the Battle of Gazelle Bay, Operation Cherry Blossom, and in Japanese sources as the Sea Battle off Bougainville Island (ブーゲンビル島沖海戦)—was a naval battle fought near the island of Bougainville in Empress Augusta Bay.
 The naval battle was a result of Allied landings on nearby Bougainville in the first action in the Bougainville campaign of World War II and may also be seen as part of the Solomons and New Guinea campaigns.
 The battle was significant as part of a broader Allied strategy—known as Operation Cartwheel—aimed at isolating and surrounding the major Imperial base at Rabaul.
 The intention was to establish a beachhead on Bougainville, within which an airfield would be built.
The Battle of Porton Plantation (8–10 June 1945) took place near the village of Soraken on Bougainville Island, in the Solomon Islands archipelago during World War II.
