The Battle of Bobdubi was a series of actions fought in the Salamaua area of the Territory of New Guinea between Australian and Japanese forces which took place from 22 April to 19 August 1943, during World War II. Part of the Allied advance on Salamaua, the battle was fought in conjunction with several other actions in the region as the Allies attempted to draw Japanese attention away from Lae, where they launched seaborne landings in mid-September 1943 in conjunction with airborne landings around Nadzab. The initial phase of the fighting around Bobdubi was characterised mainly by small unit harassment and reconnaissance operations, while the second phase saw the capture of a number of Japanese defensive positions in locations dubbed "Old Vickers", "Timbered Knoll", and the "Coconuts".

The Salamaua–Lae campaign was a series of actions in the New Guinea campaign of World War II. Australian and United States forces sought to capture two major Japanese bases, one in the town of Lae, and another one at Salamaua. The campaign to take the Salamaua and Lae area began after the successful defence of Wau in late January, which was followed up by an Australian advance towards Mubo as the Japanese troops that had attacked Wau withdrew to positions around Mubo. A series of actions followed over the course of several months as the Australian 3rd Division advanced north-east towards Salamaua. After an amphibious landing at Nassau Bay, the Australians were reinforced by a US regimental combat team, which subsequently advanced north up the coast.
